You heard it from the infantile sophists here: it’s a matter of liberty!
(They say, while they put on their mandated seatbelts and look into the federally regulated rearview mirrors!)
Shooting a gun in public should be permitted then - according to you - because it is an issue of "Liberty".
Fools find foolish reasons to justify their actions.
Even our forfathers realized that laws were required to protect ourselves from foolish, inconsiderate people. That is why such laws are made - to protect the rest of us from the fools among us.
Rear view mirrors were a matter of good logic and had nothing to do with Federal Mandates.
In regards to seat belts you might be surprised to know that many people that owned early model cars tied themselves to their seats for fear of falling out when bouncing around on improvised roads - a logical device that the human innovation stumbled upon to protect themselves while driving. Children groceries and even adults were either held or strapped to various improvised points which was the precursor to seat belts.
As cars improved those belts (usually ropes) were discontinued. I recall my own parents using ropes to keep grocery bags from tipping over.
