Mostly to avoid death or [FURTHER] physical injury - yes.
In snooker [a.k.a. billiards], there are basically 147 points on the table per frame. Whenever one player has won significantly more than half of those points, the other player generally concedes that frame when it becomes his turn - even though there is the remote possibility that the player who is behind could catch up.
You should probably add that there are fouls in snooker (usually because of "a snooker") which makes comeback possible when under half points, but even then players usually concedes if lot of fouls would be needed to catch up.

I've never argued that a person should be compelled to resign.
A person should either resign a totally lost position or play it out. I want to know in advance if my opponent routinely decides to milk the clock or play a Death Gambit in correspondence when losing.
Also, I don't mind if a player uses all his or her time. It's the players who play at a reasonable pace but once they drop material start making their moves at the end of the time limit.
...Sometimes they slow down, because faster pace made them blunder, and now they want to think it over before they play the. You cant rule out that possibility.
This would be of course applicable to a middlegame with a lot of material still on board.
Stalling with lone king (or with little material) against (say) several heavy pieces would be rude IMO.
