A lot of regulations are just Natural Law. For example traffic tickets and pollution regs are some type of pointed gun problem, bankruptcy law is a defense against creditor harrassment, insider trading is fraud because when you buy a stock you are assuming the company wont just shill it, discrimination is a damage against shareholders because the company is supposed to hire on skill and not nepotism. Immigration laws that seek basic identification documents are also a fraud protection. Various product laws are also fraud related, its fraudulent to sell products that kill people.

Income taxes are enforced by the bank levying your wages, not the government, so they are just a deposit fee. Banks dont oppose the government. Literally everything in libertopia is just a welfare state.
