Agreed. Humans are dangerous which is why it's no surprise a country awash in guns has so many gun crimes. If guns didn't make people, whether violent or not, more deadly, there would be no reason to own one.
Gun control isn't a "punishment." You have traffic police observing drivers on the roads everyday. Yes, people slip through the cracks but it would be much worse if they weren't out there. No one considers the policing of all motorists to be punishment.
I don't thinks it's unreasonable, for instance, for people who own firearms and have minors in the household to occasionally receive visits from the state, county, or municipality to make sure they are actually responsibly storing their weapons.
