Im not asking because I dont know, Im asking because you seem to think you know
You dont need public services or instruments of state, apart from the mechanism of money, to earn money. But even then, during periods of our own history there were different forms of money before that became standardised and controlled
But thats a massive stretch to saying to that poster that they can ONLY earn money because of the various state run provisions that there are such as healthcare, education, roads, utilities (state subsidised), armies etc etc.
People have been earning money long long before those things came along and even worse in those days any taxes raised were literally just for the kings coffers, it wasnt to provide the public with supports or provisions at all. No one got anything 'back' from any taxes they paid.
