What paid for the roads he took on his way to music classes? What funded the internet he made money off of? What paid for the tanks that kept his country in such a state that people could spend time studying music rather than fighting civil wars and subsistence farming?

If everyone gave their money to helping other people with their hobbies, rather than paying taxes, would you want to live here?
