Oh well, I'm talking about getting rid of all taxes 
What system do you propose for paying for schools, roads, hospitals, emergency services etc?
People can pay the service provider/producer. Same way you pay for food, clothing, housing, etc. It's called trade.
And what happens if you can't afford any of these things? You grow up without an education, are homeless and starving and left without any prospects or future, and eventually you'll die when you have a minor injury that's left untreated.
How do you pay the police? They come investigate a crime then bill you for it?
