Voluntary taxation might be taken as just asking people to pay taxes which I am thinking is a bit of a strawman. If instead you chose to pay for the services you wanted and subsidized services for others you could end up with the same system we have in total expenditure but with an added layer of feedback where government services "compete" for the polity. Naturally reducing the overall bloat of our institutions.

I don't think that re-engineering the incentives around taxation means we have to go full Ayn Rand. I also don't think any of these ideas will come about from people deciding. The natural advantage the wealthy have in choosing where to locate their capital will force this outcome with governments coming kicking and screaming the whole way down.
