I man....so how's that going for all the tiktok kids in gangs in the inner cities showing off their giggle switched Glocks....and no one does a damn thing...you live in lala land or in an ivory tower so bright no one can look directly at it.
If you get caught with a gun that hasn’t been transferred to you legally, you BOTH go to jail. If it was used in a crime, you both are punished equally for the crime. 
All firearms should be registered. I can’t see a situation where it would be unnecessary. The money used for registration can be given to the innocent victims of gun violence.
Yes, if they want the privilege of owning a gun they should pay for registration as well. We do the same for cars and those are arguably actually required for a lot of people to work and live.
You can buy a car at any age, without registration or a license or insurance, you can transport it across state lines with no issues...and then drive it on private property with no restrictions. The car analogy is a terrible one
Actually with the new proposals to remove firearms from anyone with any kind of criminal background or mental health disorder, and the law being amended to allow this, there are ways to effectively stop people from having firearms. It's simple humanitarian guidelines that need to be enacted. Only a churlish dolt would refuse to see the common sense of keeping guns out of the hands of men and boys.
Since you asked me this twice, I will not answer it again. But I will touch on the black market part, no one can enforce the black market and that’s why it’s called the black market. but just because the black market exists doesn’t mean legal market shouldn’t. if you think a firearm shouldn’t have to be registered legally because it’s possible to get it illegally, then you are missing the whole point of laws and civilization, and I’m not really sure why you’re here. 
Registration is a tool for oppressing minorities. It's racist, and thinking registration is going to magically stop gang violence is hilariously naive.
Not sure I said anything about gang violence. But clearly you’re a white male if you think a simple gun registration is racist. Is car registration racist? Don’t get me started on gun insurance.
I'm actually not, nice try though. But gun laws have always heavily been used as oppression tools towards minorities. The reason I pointed out gang violence, is because that's where 85% of our gun homicides come from.
Just an FYI...the car and gun comparison is silly. You can buy a car with no BG check, at any age, for cash, transport it across state lines, not register it or have insurance and drive it on private property at any age.
