The way I see it, it's a package. The internet is supposed to be a network of peers. Keeping this property is important for a number of reasons, both technical and political.

To be a peer on the internet, you need to be able to be server as well as client. With current protocols, this means a public static IP (or range thereof), symmetric bandwidth, and no spurious restrictions. The network must also be "clean". No deep packet inspection, no transformation of payload, no NAT, no nothing. Just a dumb pipe, who treats packets equally —for some definition of "equal". And if you have difficulty handling a particular kind of data, then just install bigger pipes. Congestions should be few and far between.

Some people would go even further, arguing that you also need an Autonomous System number. I believe this is less important, though I tend to agree. People should be their own ISP if possible (hint: it's difficult). One way to do it is set up a non-profit, and be a member.

Now let's get more technical. The main reason why consumer upload should match consumer download is this:

Worldwide upload = Worldwide Download
(Modulo lost packets and multicast.)

> I don't think there will be any demand for greater upload bandwidth until using that bandwidth isn't an event that totally swamps your connection and requires manual coordination with other users.

Actually there's already a huge demand for upload right now: YouTube. Every time someone watches a video, Google must spend that much upload —without requiring the attention of the account owner. This makes the network unbalanced: lots and lots of data are pouring out of Google's network to the consumer networks, and little ever goes back.

This has economic repercussions. Basically, ISPs connect with each other in two ways. The first is Alice and Bob having a peering agreement: when Alice can send data to Bob, and Bob can send data to Alice, and no one charges for anything. Then you have transport ISPs, which charge for the data you send through them. That would be Eve charging Bob for transporting a packet he wants to send to Alice. (When Alice and Bob aren't directly connected.)

Normally, an ISP wouldn't charge for any data for which it is the recipient, because that's data it wants, after all. But that's not exactly the case of consumer ISPs, whose purpose is to transport the data to the consumers. So they charge the consumers themselves. Now here's the problem. If the bandwidth was evenly distributed, the ISP would send roughly as much data as it receives. Perfect for peering agreements. Instead, they keep receiving more and more data. So they're tempted to act like a transport ISP, and begin to charge for the data they receive. Except that won't fly, since their network is the destination of that data! Which is probably why they try the "middle ground" of merely slowing down data that isn't paid for, destroying any illusion of Net Neutrality in the process.

There is also a technical reason: a really peer to peer network would have the data travel shorter distances, instead of say, going back and for the capital even when two neighbours are talking to each other. That means less Tbm (TeraBytes multiplied by meters), which is ultimately cheaper.

> I have a static IP option for $6/mo

Your ISP is a crook. Static IP cost them nothing: most people are connected at all times anyway.

> So I don't see much point trying to lobby ISPs for larger upload (esp when it goes against their technical constraints. […])

It doesn't go against their technical constraints. If it ever does, it is because of constraints they put in place years ago with the advent of this infamously asymmetrical DSL. It's their fault, and the onus is on them to update.

Overall, try to step back from your own situation, and watch the big picture. This often yields different answers. (Example: if Joe Random wants more money, a way to get it is to become "more competitive". But if everyone gets more competitive, Joe Random will rank just as before.)

So, regarding the Chicken and egg problem… Sure, if you suddenly had a static IP and smoking fast upload, you may not behave any differently. But if everyone gets that, you may have a market, and it may change things. If anything, it would make overlay networks more practical, and goodness knows what innovation could come out of that.
