You must be a delightful dinner companion.
Fine, that's a cavil. This is not: Disk is cheap. My time is precious. It's a lot quicker and easier to just dump everything into a big greppable bucket, on the off-chance that five or ten years from now I might need to fish something out of it, than to spend hours or even minutes picking and choosing.
Of course, excepting a reimage after disk failure, the odds that I'll ever actually need to pull something out of my backups are low -- but if the dice ever come up snake eyes, I'll certainly be able to retrieve whatever it is I'm after, while doing things your way has the same low-but-nonzero chance of needing to go fishing, plus a nonzero chance of not being able to retrieve whatever it is because you didn't think it was worth backing up.
You present your attitude toward backups as originating in a need to suppress what must be an extraordinary susceptibility to a swelled head. May I suggest your efforts in that area are perhaps slightly less complete than you fancy them to be? But that's your problem to address, and of course you're free to take whatever chance you please, and waste however much time suits you, in pursuit of that admirable end. Me, I'll just keep shoveling everything into a big cheap bucket, on the off-chance I'll need to fish something out later on.
