You are missing the whole point. If those representing the Biden thuggery steal the election they are not going to constrain the making of toilet paper.
If the election is stolen and our president is no longer in office, the ammo and weaponry and means of self-defense will no longer be manufactured; no more will the shelves fill themselves with shell-boxes. The firearms for sale will be few, and many, many others will be taken by force.
Ask an Austrailian, or a Brit, or a Canadian for that matter. You might want to buy some extra toilet paper after hearing what he says.
I understand and agree with your concern about liberals.
However, the point I made about supply and demand is an explanation of the present and not about what a Biden administration would do. Presently, we have a pro-2A President and Senate. Presently, manufacturers of guns and ammo are not being constrained by draconian laws - except in certain states like CA and MA.
Guns and ammo supplies will catch up with the demand under current government laws and regulations.
To your point: if the libs get control of the White House and/or Senate and/or SCOTUS - everything will be liable to change - for the worse.
