If your child is not vaccinated, they should be barred from attending public school

Sure, it's a big no-no here as well. It's very expensive and you can lose your driving priveleges for substantial periods of time. Yet drink-driving accidents and fatalities happen all the time (significantly more than firearms fatalities/injuries).

My point wasn't any particular risky behavior, more to show how broad the issue can grow pretty quickly. "State having a vested interest" gets into a LOT of rights-trampling before you can say "Kelo v. New London".

Interesting side note: The corporate interest that asked the local government to seize and demolish the housing through emminent domain changed their mind and de-invested in the area. The area is now an abandoned rat's nest littered with construction debris. I raise this point to make the case that Government most certainly does NOT always know what's best.

Over here, the most powerful lobby group pushing for restrictions of individual liberties is mothers. Pretty much a single monolithic interest in key areas, politically impossible to deny, and very keen on ensuring that their kids will never face any kind of risk or discomfort whatsoever. Even if the government doesn't want to impose restrictions, once the mothers' lobby wants them, they'll get them.
