I'm pretty sure we just covered this. And I'm pretty sure you have no intention of addressing my chief argument (because you can't, wimp!). So this is the last I'll say of it on this thread.
Libertarian allows for pollution control, roads, food control is a reach. We would simply use a road tax to pay for roads. They do it in New Zealand, you pay by the mile rather than by your income! It would be easy to implement here by paying for all roads with fuel taxes, which are already in place at a lower than necessary level.
Naturally that gives the dissenters the right to not use roads and not pay for them. I would be willing to bet that there is a real life example of this somewhere where some woodsy dude doesn't want his taxes going to pay for roads that are purpose built for gas guzzling cars. He probably walks everywhere and thinks we all should too.
Encapsulated in the road tax business is pollution control. Tax gas, less consumption.
Food safety need not be the realm of government regulation. Take home made jams that are sold at farm stands (or farm stands for that matter). You take your chances. Grow some balls.
For the record, both sides of the isle have a free loader problem. Its hardly grounds to dissolve your ideology. So some people ride the bus without paying, big deal! You won't invalidate the road tax idea just because you couldn't tax the foot traffic would you?
If Libertarian ideas were a fallacy no one would be able to navigate a sidewalk without a pamphlet from Basil.
