No it is not, for a very obvious reason: you get all the advantages of living in a society. Even just for infrastructure alone. Roads, sewages, electricity, internet. Last but not least, safety and order. Any income you might have developed is built upon this foundations. It is the very minimum that you pay back for it, especially if you have more than most others. The only thing I don't like is that we don't have a choice about it. We are born in nations and we're subjected to their laws, like it or not. But you can still give up everything and not pay taxes...
