It seems like in such an open organization, and considering the problems (1%) that this is trying to address, there would be some tools for querying the wealth distribution. (There may/should be, idk; a few Googles came up empty.)
I could even imagine automatically refunding the fee for those casting losing votes to avoid wars of attrition... I guess that's essentially an auction.
Anonymity on the internet pretty much inherently means that you can't tell how many actual individuals a given set of apparent individuals really are. You can tell how much money they have (or CPU power, bandwidth, or various other proxies for wealth), but that's about it. I don't see how this wouldn't be an inherent problem for any cryptocurrency (or crypto-whathaveyou-system) attempting to force decentralization (see; the primary actors in Bitcoin split war.)
