Gun control has nothing to do with guns and everything to do with control.
1 - make it so felons lose RKBA
2 - make more and more crimes a felony
3 - people who care about RKBA spend time/energy avoiding becoming felons instead of living/promoting RKBA
4 - PROFIT!
stay safe.

Don't forget voting rights, which is the other primary form of power we have over our government. Actually, voting comes before guns in that regard.
Make everybody a felon, and the government can do whatever it wants.
Or, less conspiratorially, "felonize" everyone who does something (has guns, smokes pot, or whatever), and POOF!, the majority of people who care about that something enough to vote against its prohibition are disenfranchised, unrepresented, and unable to vote against their incarceration.
This way yesterday's majority can impose itself on a future majority which may oppose the laws of the past.
Why was this done? Because God forbid those [insert generational youthful anti-establishment culture here] ever grow up. Originally it was hippies. Today, it's libertarian-minded young adults.
