Writing laws and regulations only affects lawful people.

Gun ownership is largely a regional thing. In rural America, it is hugely common to see a gun rack in the back window of any pickup truck (by far the most common vehicle). Many of the people I've met in farm country are firearms enthusiasts who own semi- and full automatic rifles, 50 cal sniper rifles, etc. The fact that almost everyone owns multiple guns doesn't correlate to increased rates of violent crime. The fact they many of them own assault rifles and other military weapons doesn't make them violent people.

Regulations do not make anything harder to acquire; they just increase the price and risk of acquisition. Illegal guns and drugs are readily accessible to anyone who wants them and is willing to participate in the black market.
