I do not agree.
In real democracies you always have the option to no longer be a subject of the government, and as such you don’t need to pay those taxes. You can always leave, most people just don’t do it because it is too much of a hassle.
This is simply not true.
First, the whole planet is occupied by nation states. The only choice you could have, would be to choose a new master. This would not change anything substantial.
Second, the nation states have designed rules - similar to the slaveholders in northern America not too long ago - and established them on a nearly global scale.
You are not allowed to live or work in a freely choosen part of this planet. Even not if you are able to prove that you are self-sustained. It is Slavery, it is Serfdom, it is Exploitation.
