I think the problem with 1) is that we need a consensus building process to arrive at consensus as to which consensus building process we are going to choose. It's a chicken or the egg kind of problem. And I think with 2) we need a genius to come up with a solution that allows that all people have a fair say somehow.
As I brought up the last time you started a thread asking this very same question not a month ago, the Counterparty protocol on the Bitcoin blockchain has a token voting system that can be used and is transparent on the blockchain.
Create a named Counterparty asset, distribute asset for a nominal Satoshi (proof of Bitcoin ownership/usage) then distribute voting tokens.
It's not rocket science.
