Many have discussed this point.
One idea: have a one-account = one-vote mechanism in addition to Staked SPS. This would work with the current KYC program launched for KYC tournaments. KYC account = 1 vote.

For any proposal, it requires 50% vote from KYC accounts to get to DAO vote, then it is 2/3rds of staked SPS vote to pass.

While there are many die-hard Web3 purest who resist KYC, those types can load up on Staked SPS to still have significant voting power.
