Poll tax/proxies: You'll never convince me that proxies aren't undemocratic. That's beyond the fact that they utterly destroy your ability to take quick votes, which is more of a logistics issue. I remain convinced that you'd get a far better result with a representative democracy if your goal is to enfranchise all members at the legislative generation stage.

I think "popular ratification" (replacing the current second year vote with an up-down vote of all members, attending and non-attending) is a better solution than the nightmare that proxy voting would rapidly become.
