We lost the Chinese & Russian imports of guns & ammo in 1994. What did we get in exchange? Nothing. Well, we got much higher ammo prices, so there's that.
We lost affordable full-auto guns in 1986. What did we get in return? Nothing.

Almost everything changes over time.
So, one can sit back and watch things change in an opposing direction;
or, they can become active in promoting the change they can live with.
Ahhhhh, choices, life is full of them . . . . . ..
