I'm not for a minute suggesting that there will be no taxes. There will always be taxes. Just pointing out the reality that taxes are extortion backed by violence. Prettify it however you want, but Might is Right and force is used to extract wealth from the weakest. Sometimes the weak rebel, and then society gets turned upside down, and then in short order you have another group of wolves shearing the sheep.
The idea of a society where the strong don't steal from the weak at every opportunity hasn't been tried since we stopped being hunter gatherers.
