"Render unto Caesar the things which are Caesar's, and unto God the things that are God's" - Matthew 22:21

The Christian doctrine says pay your taxes. Jesus said to pay em. Yes, Christian ethics does not consider paying state taxes to be immoral, rather, it is a duty. The ancient people were smart enough to not accept fiat currency, they wanted coins of silver and gold! Ancient civilizations had far less trust.

(Not religious myself but wanted to offer another data point to this).
