What is involuntary about it? It says "let's say you COULD," not "what if the rules changed." It's a voluntary option to get out of paying taxes, and I think it does a pretty good job of simulating what it would be like if we relied on voluntary contributions. The thing is, you all say that support will come from voluntary contributions, but when it comes time to actually, you know, contribute, all of you will be passing the buck. It's because it's not about the ideal, it's about the money, so stop bullshitting and acting like it's not. If the government charged no taxes, I assume a lot of you would care much less about getting rid of it.
