In my case, I believe pretty strongly in property rights, and I believe intellectual property rights (as they are called) are incompatible with real property rights. Therefore, "pirating" anything is at least legally permissible. I don't intend to argue that point; you asked to understand and I'm explaining how I think.

> From my perspective, a musician put forth a lot of effort and cost into creating a piece of music.

And, sure, it would be nice if this musician were rewarded for his efforts--if it became a financially viable operation--and if he (or aspiring musicians who know of his example) were encouraged to make more good music. However (according to my view), once he puts his music into digital files and someone puts it on the internet (which is more likely the more popular his music gets), he has no legal way to compel anyone who downloads it to pay him for it. At this point, I'd say, "Yup. So he'll have to be somewhat creative (or get good at performing live or something) if he wants to make much money as a musician."

Yes, it's possible that few people will pay him, and he'll be forced to go out of business (at least partially) as a musician. Sure, that'd be unfortunate (assuming his music was good), but that's the way it is. You may say, "This is unacceptable! There needs to be a legal fix for this situation." I say no; if you looked around and thought for a while, you'd see that situations like this are really not so unusual.

Suppose I'm a student at a school and I'm a member of some club (math club, if it makes a difference), and I come up with a fundraising idea: host a dance on the Friday after exams for the academic quarter are over, provide food, and sell tickets. And it's a success: the math club makes a good profit, and we expect to do even better next time. But, now, when the next quarter rolls around, a different club with more advertising capability sets up their own dance and attracts most of our attendees away. Their dance is an even bigger success, our second dance turns out a loss, and we in the math club have no reason to expect the same thing won't happen again next time, so we discontinue our dances. Now that other club makes a profit and we get nothing; had I realized beforehand that this would have happened, I might not have bothered.

This is unfortunate, isn't it? But I don't think even the most hardcore pro-copyright, pro-patent advocate would claim that I or the math club had the right to a share of the other club's profits, nor that they were infringing on anything that could be called my "intellectual property". Our only recourse would be this: we could go to the other club, say, "Hey, you guys are benefiting a lot from what was our idea, and we're getting nothing; you really should cut us in on some of that," and if they said, "No, fuck you," then we could spread the story and smear them as ungrateful jerks (which they would be). Also, threatening to smear them as such might induce them to pay up. But legal action? No.

Suppose Apple spends a large amount of time and money on research and development, and it concludes that a) PC's are going to be displaced by tablet computers and b) a tablet computer should optimally have a x b x c dimensions. Then other companies simply trust Apple's judgment; they cut their PC R&D budgets, start developing tablets, and make them approximately the same size. Their products are successful, and they suffer little when PC's do eventually decline. Again, no one could claim this is intellectual property violation even under today's laws. But these other companies are benefiting from Apple's hard work, and Apple has no way to demand (and get) compensation.

And suppose I set up a big museum, and it's very successful and brings in a lot of visitors. Many of these visitors buy food at shops next to my museum. I have brought the owners of these shops a lot of customers that they wouldn't otherwise have gotten; they are benefiting from my hard work, and I have no way to make them pay for it. (This can't be intellectual property--it doesn't even have to do with ideas.)

So there are cases where someone can do a bunch of work and make something good, and other people benefit a lot and the original person gets very little in return, and yet this person has no legal recourse to make his beneficiaries pay him. These situations happen. They'd be less likely to happen as the people in a society become more prosperous, generous, and civilized--which suggests what I consider to be the proper solution.[1] On the other hand, trying to patch over these situations by fucking with the legal system is asking for all kinds of trouble (and we're getting it). I'd hate to see the legal system that resulted when someone patched over every case I listed above.

[1] In the math club example, if the people in the second club were nicer--or if the main body of students had a strong sense of fairness that would be offended by ungrateful jerkishness, and the second club cared about their image--then the problem would be solved.

Now don't take this to mean that my beliefs are utopian and therefore irrelevant. I've said that the default situation--that there are cases where people make great things and benefit many others but get little in return--is unfortunate, but a fact of life. Clearly I don't think the world is perfect or humans are perfect; nor do I expect them to become perfect in the near future. I said that things would become better, that unfortunate situations would become less common or less unfortunate, to the extent that civilization advanced and humans became more generous. I consider this an excellent reason to want to improve the human condition, to make everyone more wealthy.

(Oh, and, if someone goes around claiming that people who pirate copyrighted stuff are "criminals", "thieves", "depraved"--or, for that matter, on the same level as actual pirates who board ships, kill people or take hostages, and steal or wreck the stuff on the ship; or if someone goes around attempting (sometimes successfully) to use the legal system to extract or extort huge amounts of money from "pirates"; then I'm most certainly not going to feel like an ungrateful jerk if I fail to compensate them for downloading something they made.)
