Everyone understands that public services are free to use because they are funded by taxes. It's not the gotcha you think it is. People say that roads, K-12 education, etc are "free" when they mean there is not a direct fee to use them because they are paid for by the government using tax dollars. You don't have to pretend to not understand this
I'm not pretending to not understand here. Someone said it would be free and I'm asking how. The fact that "free" doesn't mean free is the problem, not an issue of me misunderstanding.
