[GTA V] Why are civilians allowed to buy tanks and other military-grade hardware so casually?

It seems like any random twit can walk into a shop and purchase guided missile launchers or squad machine guns without as much as a criminal record check, not to mention online purchase of fully armed and equipped tanks. How is this possibly legal?

It's a natural part of the libertarian ideals that permeate the culture of the GTA universe. 

Wanna drive down the freeway at 300MPH on the other side of the road? Go for it, buddy. Wanna walk around with a rocket launcher and grenades? Hell yeah, this is San Andreas! Heck, this great nation even has a city NAMED after Liberty!

That said, that level of freedom is kept in check by the rapid escalation of police / NOOSE / military response to any acts of violence. If you start shooting up the place, they're not going to waste time trying to arrest you—they'll just gun you down as quick as they can.
