I have found it sensible to characterize taxation as a form of extortion. This is what it was when monarchs claimed that they owned the realm and everyone who occupied a part of it had to pay them for the privilege of utilizing it. Monarchs–at least many of them–believed that they own the country they happen to rule (because, some argued, God appointed them the caretaker of it). So if you make use of any portion, you need to pay them (taxes). It was just a “fee” extracted in return for the privilege of dipping into the monarch’s property.
