You are again free to leave. It's a relatively simple social contract. If you take something from society, you'll have to pay for it.

If I go into a walmart and take products off the shelf, Walmart also expects that I'll pay, and will enforce that under threat of violence.

I'd gladly switch to a voluntarism based society, but it turns out the vast majority that claims to support voluntarism just wants to take advantage of society without paying for it.
