Do you go to grocery stores? Guy walks in, buys a knife, goes to the entryway and stabs 2 random people. Stopped by a guy with a CCW.

Nice try, but no. You're on the "I've never felt the need for one so why should you" kick. A Libertarian doesn't care what you do as long as it doesn't hurt them or others in any way.
In the 6+ years of having my CCW, I've never needed it. Doesn't mean I didn't put on my G30 today.
