This isn't just a theoretical question. Suppose you are some rich old guy who can put several machines in his house, or just use a barbell, dumbells, an adjustable bench and squat rack without a spotter.

You don't need a spotter if you have a squat rack because you can set the pins to a level where if you do fail, the bars will catch the weight.

Yeah the only thing you can't do without a spotter is barbell bench press. But that's not a big deal since you could use dumbbells instead.

You can set the pins so that you can safely bench. I'm not sure how useful bench press is for most of us, but that's another topic.
