And this has nothing to do with whether or not taxation is "moral", or anything like that. It's just that it's a faulty system to begin with.
Can you elaborate on that some more, because I understand that taxes are immoral because coercion and forcing people is wrong, granted everyone in this thread is happy to fulfill this "obligation" by their responses, it sounds that you conclude that because you'd give them a choice over how much you'd extort from them based on their response instead of simply extorting them without asking "do you think this much extortion is ok", and that somehow is better.
To put it differently, you're asking people if "is just the tip ok or how much would you like me to penetrate you" and then proceeding to rape them based on their response, arguing that this will be a better way to rape people, because outright rape is "faulty", and limited rape is not.
