Ask yourself (1) " do you own your own life"?
(2) " are you willing to grant others the right to own their own life?
If you don't own your own life, you are a slave!
If you don't want others to own their own life, you are advocating slavery.

To own something is to be responsible for it. In our society, we often are not taught that we are, and ought to be, responsible for our own life.

This flow doesn't take into account that customers become criminals. Outlawing anything for the purpose of protecting citizenry is dumb, I feel. The net result of this is not greater safety, but less freedom. Look at the mess the war on drugs has made. Huge Central American cartels exist and prosper because of it. Who knows how many addicts are in prison (customers now criminals).

It is a real conundrum. However, some things need to be banned or severely curtailed. The gun deaths and destruction clearly point that out. Cigarettes are another issue and the regulating of this item has had a positive effect.
Sometimes the availability of a product makes it more accessible. This accessibility makes it easier to get the items and addictions can go from there. I once read a report about how guns actually change the way people think (it was a German study so what do those people know - I'm being sarcastic)!

I’m ok banning people from having weapons of mass destruction, like bombs and missiles.

Now, where to stare the line? I think drawing it at automatic guns (like we did long ago) is good.

Drugs? Legalize it all. No company would sell the ones that mess you up, cuz, liability.

Hold people accountable for any stupid shit they do while under the influence.

To be honest, I'm okay with severely restricting most narcotics and perhaps banning some. I don't necessarily think we should kill the dealers, but in cases where people add even more dangerous substance to illicit drugs, maybe it's warranted.

I'm not opposed to prohibitions on certain individuals owning guns, but I don't support banning guns either. I don't think convicted violent criminals domestic abusers, or suicidal individuals should be permitted to possess guns, but I also think that if our prison systems worked as they should, ex-cons would be less likely to commit a crime than the rest of his.

Unfortunately, we have a society where many things are prohibited to protect stupid people from themselves. This is detrimental to human evolution
