A problem with that logic is that it doesn't do anything to change the economics of gun sales.

If you kick them off the stock market, gun manufacturers can go private, or they move their headquarters and incorporation abroad.

If you prevent banks from making loans, they'll take their billions to Deutsch Bank, or HSBC, or some crypto bank that is happy to hide their money. Plus, if they're now private, there's likely no requirement to report their loans.

If we tax gun sales at 100%, you'll start to see more people renting out their guns or "gifting" them.

Are you buying a new mattress? We'll toss in his and hers handguns to keep under your pillow.

There are hundreds of millions of privately-held guns in this country. Without a cultural shift, and an active campaign to decommission those firearms, there's more than enough supply to fuel a black market for a long time.

It'd be like the war on drugs, you'd push everything underground, manufacturing would move abroad, and the lack of visibility would potentially make things worse.
