Is your back broken? Are your fingers worn to nubs? Are you physically able to work without undue physical stress? If so, then you're extending the argument to a ridiculous point.
If you owe money and cannot pay it without bringing in a paycheck, you're not at the point you should stop working voluntarily.
My fingers are somewhat nub-like, but they have always been this way.
As for my back, I do stretching exercises and calisthenics, but I have been treated for severe back pain in the past. Probably caused by sitting in my cubicle for extended periods of time. The back is fine right now though, thanks for asking!
While working, I suffered from a moderate case of stress related hypertension. That miraculously went away within a few days of when I quit working. The htn wasn't to the point of making me at extreme risk of stroke, but there was an "elevated risk". The job also involved workplace exposures that could lead to serious injury or death, although I was the one usually in charge of ensuring safe working conditions.
Does it make any difference what my job was? Some would say my job was unethical. And at least one Federal Court of Appeals agreed.
What if I was a lobbyist for the Baby Seal Clubbers of America, Inc. or the Mountaintoppers Coal Stripminers Association? What if I was a waste disposal engineer in charge of calculating the exact flow rate of toxic sludge our company could discharge into the pristine waters of a river near you?
Just sayin', with my unfettered powers of destruction, you might be best served having me at home slinging words on the computer screen instead of stacks of bens to hardworking members of Congress or right-sized toxic sludge into the inland waters of America.
