"If you don't like the terms, you are free to not accept them but then you also may not use the state's roads."
Drink the Kool-Aid much? The "state's roads" are part of the commons. They belong to everyone. The illusion that the state has to somehow grant me the privilege of being on public property is an outrageous fabrication. (Hint: Where is the public land where it's not a "privilege" to be there, in your estimation? Oh right, there isn't any...)
So, why don't you go out in the street and dg up "your" part? Ditto for "public lands" like BLM land, National Forrests, National Parks, National Monuments, the cpital, the White House, etc. Just walk right into the White House and say you want to stay in "your" part. Better yet, try it with a nuclear sub or an aircraft carrier.
The answer is that it is commonly accepted that government, on whatever level, "owns" and thus controls these properties. You can protest all you want that you are just taking "your" piece of whatever public property but the cop and the judge and your jailor won't care. I don't agree with governemnt controling the roads, buildings, etc. but I won't try any of the above.
So, go take a big hit of your hard core, libertarian Kool-Aid and then knock yourself out seizing back your property from the government. I'll quietly work at convincing people that the government shouldn't be in the business of running all of these properties. If you're lucky, you'll at least have the satisfaction of serving your time in a privately run prison.
Cheers,
