Every single craftsman I know have abandoned their craft for something else because of body issues or injuries. Also, you’re nowhere as nimble at 50, 60 or 70 as you were when you were 20 or 30, so the risk of work related accidents increases, assuming you’re still doing the same tasks.
This is a good hypothesis. Whatever the reason, I see no evidence for old roofers causing death or injury to anyone, including themselves. There is zero hypocrisy in regulating old drivers while being laxer with old roofers.
Nice theory. Doesn’t work in practice. Most societies are not okay with people taking excessive risks, even if it only impacts them. It’s why we require seatbelts even for single-occupant vehicles.
I for one use seat belts, and I want them to be required to be manufactured in vehicles, but I believe it should be a personal choice whether or not you wear them.
My point is whether it’s others who are dying is irrelevant. We have evidence of increased mortality with age for driving. I’m not seeing similar evidence for roofing. If geriatric roofers were constantly falling to their deaths, we’d see a movement to regulate them, even if they’re falling on flowers and not people.
