Further, these sweeping, context-free, a priori exclusions place a significant restraint on trade, speech, and namespace usability. As an individual, as an end-user, and as a stakeholder, I don't see this as detrimental to the proper functioning of the net. Nor do I see it as detrimental to myself or others like me. Preventing this kind of exclusion doesn't increase consumer confusion, either.
Consumers seem to be more than able to find the websites via which they'd like to spend money.
I see no reason to further restrict namespace with these kinds of policies. Namespace is not just for commercial interests, and it's not just for web pages. Ten years ago, many of you would never have predicted the Web would even exist as it does today. And DNS will similarly be put to myriad uses that aren't yet imagined. Unless, of course, it only applies to mark holders.
