Then I would suggest you go live in the middle of the Amazon or the heart of Africa, or an island in the middle of the ocean.
Sadly, without income tax, there is no money to build roads, provide policing, implement law, etc. Once you have lived without law and order, running water, and other modern facilities, including educated people, perhaps you might realize that it is ludicrous to believe a country will work well without some form of central government. And government's require taxes.
Nobody is stealing your money. That money you pay is the price of admission to a civilized society.
I have no time for libertarianism.
