How would you design a governance system that allows people to pay for the policies they want (direct bribery) but doesn't become a plutocracy (where only the rich have a voice)?

The only problem is externality pricing.

pretty easy actually-
1member: 1vote and financial returns/dividends are proportional to $ staked/invested/provided

hard part-
getting to 1member (aka Sybil resistance or equiv)

Thoughts on zk-applications that introduce secret ballots like MACI? The voter cannot prove what they voted for and can only prove the fact that they voted. This would prevent bribery between untrusted parties, but not necessarily between trusted parties.
