I think there are very few people who are advocating for that level of disconnect in a TTRPG environment, even if they do prefer to have scaled challenges.
If you want to play a game where the challenges stay within a certain difficulty framework, as a GM you need to frame challenges that are thematically relevant to the PCs at that point in time. If you introduce a pack of goblins as a level 1 challenge and the PCs don't interact them, I don't think anyone is advocating scaling them up to level 10 just because the PCs came back a few months later.
Now, that doesn't mean you can't recontextualize the challenge; maybe leaving the goblins alone allowed them to steal a magic item, and now they're all possessed by powerful demons. But even then, doing that sort of action should only be done occasionally less it seems artificial.
