I think you're totally missing my point. Not only the government encroaches on your freedom. You can't just look at the highway regulations as encroaching on your freedom without also looking at the guy slamming into your car* as encroaching on your freedom too.

* which may be the direct result of a lack of regulation. See: Montana.

The corporation polluting your water source is encroaching on my freedoms. People that break into your house encroach on your freedoms. People that breath smoke in public areas that give other people cancer encroach on our freedom.

More saliently for me freedom involves fundamental choices. People want to say what they want, read what they want, go where they want, do what they want, eat what they want. Kids that are undereducated have their choices (read: freedom) massively curtailed. People that live in an area where everyone is a farmer have their choices (read: freedom) massively curtailed. If I want to get thai food for dinner and there's no thai restaurant for 300 miles my choices have been curtailed. If the local library doesn't stock Harry Potter my freedoms have been limited. If the internet is too crappy for netflix my freedom is limited compared to elsewhere.
