There is a difference between wasting your own money and taking other people's money by gunpoint and wasting it.
Private enterprise doesn't need something as crude as a gun to take your money from you. They convince idiots such as yourself to give it to them willingly, sometimes even when you know you are being cheated. And the meme that taxation = theft is tired, false, and stupid. If you really believe that then move to one of the locations where they do not tax you. Quite a few exist though they aren't pleasant places to live. But you don't get to take your roads, police, health care, utilities, fire department, military, etc with you. You get to fund those all yourself with "your money".
Seriously, get over the notion that you don't depend on other people and that you have no shared responsibility to society.
