I don't pay taxes to McDonald's and yet they're still there to prepare food for me if I so choose to give them my business. There's no reason why we would have to go back to a hunter-gatherer society with no income tax, or any replacement for it, and in fact we'd have more money to spend on food. We also had roads and bridges before the income tax as well.
You didn't specify 'income tax'.
There are only two types of roads built: roads funded by tax payers and shared by all and roads funded by private interests and charged for use accordingly.
There are some projects that We, The People should fund and own collectively.
Government is not THE answer but it is AN answer and only a fool leaves so powerful a tool unused because it burned him once.
Well I see all taxation as theft, but I thought we were discussing the income tax specifically since you mentioned the fair tax. There really isn't anything that "The People" can own collectively. How do I exercise my share of the ownership of something that we all own? It's impossible.
Just hop in your private vehicle and drive across country on public roads.
We, The People collectively own the interstates and, as one of The Peeps, you're free to drive them ad nausea, provided you comply with the rules, as established by We, The People of the various states the roads cross.
Government IS a useful tool, as long as it's held in check by fair taxes and a budget balanced by law.
