Yeah. I have a question!
Why is it only those that own the means of production that get a vote?
Simply, because it is the easiest thing to do.
You could make a proof of stake vote. It takes some preparing, someone needs to collect the votes. More importantly, he/she should not be able to connect ip addresses to signatures. Everyone has to be informed that his vote is wanted and they collect the private keys from cold storage, possibly endangering the integrity of the keys. Also, this voting scheme has the problem that some big exchanges may use customer funds to vote for themselves.
Another random idea would be one bitcointalk forum post one vote, but that is easily manipulable and also not very fair.
And "One person one vote" is clearly not accomplishable over the internet.
