Theory of Games
Storied Gamist
Take a short rest people.
Is that a Joke? You started with dismissing the original problems caused by players abusing excessive rests in a system designed to guarantee successful 5mwd. From there you highlighted a path that simply leads to the GM-Alice being blamed for the resulting crapsack world as a solution for bad design & when told that substituting serious problem A for serious problem B you suggest that GM-Alice grow herself the set of horns that come with a moniker like "Killer GM".
The MAD style arms race you are suggesting only ends in animosity & everyone loses
Getting to that root cause raises the question of why you kept placing responsibility for fixing this system encouraged problem onto GM-Alice's shoulders when the system was designed to eliminate so many☆ of the mechanical tools that GM-Alice could use to not be completely powerless in ensuring that her players have realistic objectives & goals that are healthy to the table & campaign itself.Or the players could try to actually achieve their objectives with the resources they have available, instead of blaming GM-Alice for not handing them the win when they are doing their best to lose.
