Correct. The only thing required to lock someone up is power.

Well, power is another euphemism you could deconstruct as well. But that doesn't mean that you can just lock people up, in most countries. I certainly can't.

Uh, power is a euphemism? For what, pray tell?

In this case, for the ability to communicate to people who are strong to physically move someone somewhere else in a way that they will listen to. In that sense, you don't need power; you just need to be strong enough to physically move someone into a room and lock the door from the outside. Have I disproven the existence of power, or just described a component of it?
