This seems patently ridiculous. How can there be no limits just because a perspective employee can theoretically refuse?

What if all the companies decided to have these requirements?

There's an inherent power imbalance here that isn't so simple as dismissing any issues simply because there is no literal gun being held to the head at the moment of decision.

And I'll assume even you have limits somewhere. For example, predicating employment for a cushy remote via snail-mail job on a specific person happening to die... Eventually you just get to the most threadbare excuses for soliciting illegal activity.
