I’ll address those:
1. You can get autos with no external safety levers as well - in fact that type is now the most common.
2. You still have a cylinder to reload on a revolver, which is worse. And while you’re using it with ammo in it, it makes no difference.
3. Mag disconnect safeties are not present in a lot of modern automatics, or can be removed easily.
4. Um, how do you need more than one hand to retrieve and use something like a Glock 9mm? In fact, smaller people are more likely to need two hands to hang on to a small revolver in a major caliber because there is zero recoil mitigation.
5. Not proven. Some semiautos are the same size or smaller than a snubbie revolver and they don’t have nice flanges and grooves on the side for someone to grab and take the gun away, unlike the revolver.
6. Also not proven at all. I have been present at classes where people brought their newly purchased little snubby with them and they had major problems training up on it, let alone hitting anything because of the miserable sights most snubbies have. They took to the class-provided Glock 19s in 9mm a lot faster. Add to that the fact that most snubbies are unpleasant to shoot in a major caliber (not big bore, just common ‘adequate self defense’ calibers) and their ammo invariably costs more and you’ll get someone with a snubbie that doesn’t ever practice with the weapon and just carries it around as a sort of magic talisman. Been there, done that, got the T-shirt watching them.
Also interesting that you advocate a one size fits all solution for all those different individuals.
And, of course, the problem of having only one hand available when your pistol does not have a round chambered or the rare case of a misfire. Individuals with less training, experience or practice may have such an occurrence.
