People refusing to vote for the greater good because they want to preserve their own wealth (well, their wealth wouldn't be at risk but for some even given up $10 is intolerable in the service of society at large) is a great argument for not allowing them this decision. Some things should not be optional and if you want to live in a certain society you should have to help support that society's civil function. Letting people opt-in or out of critical institutions like public education seems like a road to disaster to me.
