Do you think that those sorts of people would be capable of removing a

You're a man very familiar with tools. On a bet, how long would it take
YOU? My choice of tools would be two. Crowbar and cordless sawzall with
extra battery and extra demo blade. Does that still count as two. So,
five, but something a guy could carry in a pillowcase.

Smash the drywall, cut four studs. I'd estimate three minutes tops.
