Almost all firearms regulations rests on Wickard v. Filburn, which exploded the reach of the Federal government through the same kinds of assertions on effects on interstate commerce. You might like firearms regulations, but prior to the 80's it was entirely limited to paying a tax, and registering, and event the registering part took massive contortions by the Judiciary to reconcile into assumed Constitutionality, that I frankly still find questionable to this day.
If we’re going to overturn Wickard then let’s do that. But overturning just some of the consequences of that on idealogical grounds is super weird. Especially given that the biggest proponents of gun control were conservatives in the 70s once black people start getting organized and arming themselves. Now that it’s white supremacists doing it its ok again?
