I have never used a table saw before, but from my amateur youtube understanding, safety goggles aren't perfect protection against kickback, right?
Like, if I've got a chunk of wood being hurled at my face at high speeds, I'm definitely going to prefer to be wearing safety goggles, but I can still imagine the wood coming in at an angle and knocking them away, or being hit with enough force to break the goggles.
You're unlikely to get hit by larger pieces of wood at high speed. Dust, small chunks, maybe a part of the saw may come flying at you, but i suspect they're way more likely than large wood chunks. But if you believe this photo was not staged, then safety goggles are pretty good https://external-preview.redd.it/qVMDLhaXQN8Vd9UI6d5fDswF396...
The rest of your points stand (though I suspect a saw particle colliding with your jaw is unlikely to cause damage as severe as cutting off your finger), but any responsible person will be wearing safety goggles when operating a table saw.
