Taxation is not theft, it's a non-voluntary contribution to live in some location that is attractive for many other humans to live. If you don't want to contribute, you'd need to (a) move to some place where no other humans would want to live, e.g. in the middle of the desert, tundra or rainforest, or (b) arm yourself / raise an army, claim sovereignty over your desired territory and be prepared to fight to defend your territory for the rest of your life.
