If you feel that you don't get enough of gov "care" when someone doesn't pay taxes, it means you are personally entitled to that amount that he didn't pay, right?

About income tax: imagine I work an hour and sell some artwork to a friend. How did this affect anyone on the planet so that government is entitled for an income tax from what my friend gave me?
