A bunch of things break when you do that, though I do run my osx machine that way. The point is that it shouldn't be the default, it's the end of personal computing.
With the way legislation is going these days, self hosting is becoming ever more important. RAM for zfs + containers on k3s doesn't end up being that crazy if you assuming you need to do everything on your own. (at home I've got 1 1tb ram machine, 1 512gb, 3x 128gb all in a k3s cluster with some various gpus about about a half pb of storage before ~ last sept this wasn't _that_ expensive to do)
