What? That's not an argument... that's not even logical. If people are not paying taxes then they would be able to afford the tolls... and only those that use the roads would have to pay for them. It's like you're arguing that people are being expected to work for free... that's just misleading.
Try to think of a system where everyone only pays for what they use... that what's possible with Bitcoin technology.
Sure, they'll have more money and be "makin' it rain" with all the extra proceeds from not paying taxes. Except, oh wait, their wages will probably be less than the taxes they would have paid, since there won't be any government mandated minimum wage anymore. "Oh, you want $7 an hour? Sorry, this dude's willing to work for $4. Can I get you to come down to $3.50?" That's before we consider all the price collusion they'll now face at the stores they buy goods at. They might be able to barter, but if they can't afford the privatized protection, who is to stop them from getting robbed?
This is assuming you don't mean that "omg I want the government to die so we can live survival of the fittest style" kind of anarchy. I know others tend to toss people into that mold of anarchy as soon as the word comes up, so I'll give you the benefit of the doubt and assume you don't want to pull out your bat and shotgun and win your food the old fashioned way, but if this IS what you meant, I imagine would leave most of the poor pillaged and murdered inside of 2 months by other poor, since the victim can't afford the protection and the thief can't really afford food. Presumably the thief will be "fitter" than the victim.
EDIT: This should be addressed to the 2nd guy, not you.See why this situation sucks for the poor?
We're both speculating, to be sure, but it's definitely not as simple as some of you are making it.
I cant help but find humor in the argument that people will instantly be unwilling to pay for road construction just because there is no federal government. That shit kills me.

Please show me where I said that. I said SOMEONE will have to do it, and they're going to want to make something for it, which is understandable. The problem comes for those who can't afford it, and read my logic above for why they likely won't be able to.
