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.

change conception of or introduce parallel notions of "value" different from today's 1 idea in currency. imo you reform incentive structures to correspond with their relevant realms of governance, ie. participants govern based on realm-specific merit, e.g. investors govern markets, politicians govern localities, etc.

how do you determine merit wrt a specific domain?

every domain is self-governed & independent of every other but can share resources in a federated manner at higher level. participants in each domain govern or delegate to those that make the case for decision consolidation which leads to ongoing & dynamic measure of merit. domains should be easy to start, easy to exit

merit then becomes a measure of how well individuals act in terms of responsibility and good faith. the more domains you participate in, more merit you have. more delegations you receive, the more responsible you are wrt the overall size of the domain. like a resume for trust/accountability
