Well exactly, Holden.
We're in that middle area, between anarchy and tyranny..... between having no laws and having excessive laws.
And your examples, along with the seat bell law, reside within it and certainly are up for discussion. In fact there are already laws regarding saturated fats (labels now required on packaging) and alcohol (can't drive drunk, can't drink young, and limits on where you can drink).
I'm not dismissing your argument completely. There are like, a million little laws regarding just about everything. Some are good, and some are bad.
But right now, if we could focus a little, the issue is whether or not the seat belt law is good or bad. And to consider it not by way of conjuring up Jefferson and panicking about tyrannical governments... but by considering the relationship between costs (loss of liberty) and effects (less drain on healthcare costs).
Now if you want to say that it really doesn't ease the strain on the health care system - then that's fine.... but I haven't seen that demonstrated yet.
Once again, my point is that your loss of liberty by having to buckle up is smaller than society's (everyone's) loss of liberty in how we choose to spend our money.
Going all "It's an affront to my personal freedoms!" is just a meaningless rant, even with the odd dead guy quote tossed in. It's ignoring the fact that we already live in a world with a million little laws - some of which you like and some of which you do not. Seatbelts are no different. They're either good laws or bad laws. Up for debate.
