As I have already mentioned, a person that's bleeding out requires first aid [now] - which the use of a tourniquet is a part of - and further medical attention.

Emphasis on the further medical attention, because they will simply never be able to get it if first aid is not applied. This is the exact reason why first aid exists, even though it is often technically destructive (e.g. properly administering CPR runs quite a high risk of breaking the patient's ribs).

> And a limbless person will have a much lower quality of life

A person who has lost a limb is alive, and (I digress) the hand-wringing that abled people do over the quality of life of the disabled is a bit weird.

"I'm nowhere near a hospital yet but this tourniquet has been on for ages so let me take it off and continue freely bleeding out" is frankly a foolish decision for anybody to make.
