The fact that someone has done something is not proof that it is a good idea to do it. You can shingle a roof with a tack hammer if you want, but that doesn't mean a tack hammer is a good roofing tool. I've eaten lots of steak using a table knife, but, if I can I like to use a steak knife.
Why do we never see forum threads trying to prove a 6.5x55 is " capable for deer"? Because everyone KNOWS it is (with virtually no limiting conditions on its use). Why do we see so many repeated threads trying to prove the .223 is "capable for deer"? Because everyone KNOWS it will actually kill deer (although everyone also KNOWS that you must be within the quite real limiting conditions that using the cartridge impose), but everyone also KNOWS that there are lots better rounds available, so people keep trying to justify their use of a barely suitable tool for a job.
So go right ahead and use your tack hammer to shingle your roof if you insist. People will see your new roof when you're done, but they will also have lots of thoughts about why you would insist on doing so.
Roofing is amongst jobs I would never do. Your argument is invalid.
They let people spear hunt big game. You gonna tell me that's unethical too? How do you feel about archery? Both of those techniques require you to "be within quite real limiting conditions" as you say....
