I beat dude who shoot semi-auto shotguns with my pump every day of the week on accuracy when shooting at 3,4,5 moving targets. It’s about muscle memory.
Oh, and if you are chambered and carrying and you inadvertently loose control on the weapon, they don’t know it needs to be racked.

This has nothing to do with shotguns. I've seen video of a person whose muscle memory failed when he was confronted with an armed robber. He forgot to take his safety off and started squeezing the trigger.
As for inadvertently losing your weapon, if that happens, you were never in a good place to begin with. Situational awareness should help you identify potential threats. If you let one come up close enough to you that he can take your weapon, then nothing is going to help you anyway.
Bottom line...carrying with an empty chamber is foolish and a sign that you need to somehow gain more confidence with your firearm. We can go back and forth on this forever, but you will never change my mind, or the minds of the vast majority of people who carry with one in the chamber.
