No. So you can be old and crippled and still live. If you are assuming that you will always be able to work, making the wages you make today, then you will have a rude awakening the day that you cannot. Living below your means has been almost universally good advice since the dawn of civilization. I do appreciate your sentiment however, in that there is a lot of advice from FIRE types who talk about even the most minor indulgence as some hedonistic waste of money. And it makes sense to remind those who go to that extreme, that spending money now can actually buy a little happiness. But I think you're being slightly disingenuous by taking the parent comment to the extreme of living off rehydrated beans when they're simply reiterating the idea of saving as a virtue.
