I don't disagree with anything you're saying apart from the last few words.
The solution to this problem is the same it has been for literally centuries: archiving.
The whole point of an archive is that it's out of the way and takes no effort, even more so a digital one. But if you have/need/want the time/space, you or someone else can check it, and find a gem.
As someone who by now has decades of nested digital archives of archives, those still have a psychological weight that sometimes surfaces when I am reminded of their existence. It’s not clear to me they really constitute a net benefit.
You don't have to put in the effort later. You have the opportunity to put in the effort if you deem it worth the cost then - something you cannot predict now.
