That's kind of how I feel about it, too. As the guy in the video say's, you don't resolve the problem, you just take freedoms away from those who obey the laws. That's not a solution.
Being an older guy, I also have the past as a reference. When I was much younger, legislatures at all levels were considered part time jobs. The people would get elected, spend a few months in session, and then go home to their constituents/districts. They dealt with major issues such as funding and such. Now, every one elected to office thinks it's their duty to create a new law or regulation, that will supposedly solve this problem or that. As a result we've become far less free ... and society hasn't become better for it, but more restrictive, leading to many of the social ills of today. When everything's illegal, everyone is a criminal in one way or another. So people tend to do as they please, picking and choosing between what they'll see as right or wrong.
Very true. Laws can help facilitate change, but they do not create it.
And suppressing a behaviour does not prevent it. So focusing on the tool of violence, and punishments, could never be as effective as focusing on the causes.
I joke sometimes that the problem isn't 'too many guns' but 'not enough'. If we put crates of pistols and ammo in every high crime area, there would be a temporary surge in violence followed by years of the lowest crime rates ever seen.
It's a joke that contains some truth.
A peaceful area does not become violent if they become armed. But a violent area does eliminate itself when armed.
So maybe we should stop interfering and let nature run its course.
