What if capitalism and free market forces worked to regulate firearms in the US?

The Constitution protects you against governmental actions. it doesn't protect you against the actions on non-governmental bodies.

One of the things mentioned in this clip is a landlord's prohibition on gun ownership in the lease not being a violation of the Second Amendment.

Do property rights overrule the Second Amendment?

Let's toss in for good measure that the Heller-McDonald decisions were very limited in their scope (in addition to contradiction prior Supreme Court precedents of Presser v. Illinois, 116 U.S. 252 [1886] and US v Miller, 307 US 174 [1939[).{1}

Anyway, the firearms market is pretty much saturated with companies going bankrupt.

It may not be the librul-progressives that kill this insanity as much as market forces working to limit it.


Footnote
{1} US v Miller States that "With obvious purpose to assure the continuation and render possible the effectiveness of such forces, the declaration and guarantee of the Second Amendment were made. It must be interpreted and applied with that end in view." This is the exact opposite conclusion from that drawn by the Heller-MCDonald decisions.
