Having bought both birth control and firearms in my lifetime, I believe that comparison. To get birth control, the last time I was on it, I had to see my primary doc to get a referral to the OB-GYN who wrote the prescription that I then had to go to a pharmacy to fill, and there were costs at all three levels. My daughters' competition gun, on the other hand? Same day process, with less paperwork than buying a new cell phone. The whole purchase took under an hour. We need to address the "people problem", as you call it, of bad actors getting their hands on guns; enough of these shooters have had things that should have raised red flags that it is clear the current process isn't sufficient.
And your statement about gun laws being stricter than they've ever been is outright false. The sunset of the assault weapons ban in 2004 was a significant loosening of gun regulation, and very little has been enacted since.
Bigotry, hostility, suspicion of others, hate and murderous ideologies - all of these are certainly "forms" of mental illness/instability but ultimately it's man's inhumanity to man that results in individuals murdering others in cold blood. There's also no way to refute that guns are a horrifically "efficient" way to do that and had this particular monster not had an automatic weapon, it's very unlikely he would have killed all those innocent people.
