I was going along with you till you started the crap about equating gun prohibitionists with drug prohibitionists, and equating both of them to Utopians. The one thing is not the equivalent of the other, nor equivalent to the third.
And the same argument is used by the drug legalizers/gun prohibitionists in reverse.
Let me explain in simple term that even you will misunderstand.
Prohibition doesn't work.
You can fill the jails. No doubt. But you can't stop people from doing what they really want to do. The question then is: does jailing serve as enough of a deterrent to reduce the behavior in question? Or does it increase the criminal element by promoting a black market which encourages entry into the market with economic incentives?
You need better than 99% willingness to follow the law (maybe as high as 99.9%) for a law to be effective. Once you have even 5% willing to break the law, the law is useless because punishment is not sure and jailing becomes very expensive both socially and economically. Look at illegal opiate use in America. About 1.3% of the population violates the law. The same number that used opiates before opiate prohibition was instituted. And who is that 1.3%? A large cohort was sexually abused in childhood.

And when the jailing is racially motivated?

These days that becomes explosive - if generally known. I'm doing my part to make it known.
The law is a blunt tool. And it is often counter productive. Especially so when it doesn't produce the results intended. Then there comes a clamor for harsher laws. That can go on for a long time until the law system collapses.
