Actually I now recall a somewhat recent story about a guy shooting himself while fussing with his gun in a parking lot while parked, and bleeding out in front of his family. So I'll give you that- shoot yourself in the "right" way and you will be gone quickly.

Yes, really. I said "most people" do it in a responsible, thoughtful manner. Doing so in a manner which allows it to fall out of a pocket is neither.
And since so many people pocket carry, one report of stupidity does not make it the rule.
If it's not for you, fine- but don't paint it as a dangerous practice when the numbers bear out the fact that it is not.
