Part of this is something I've been thinking about lately. We're reluctant, if not down right unwilling, to un-invent things. By and large we've generally invented things that improve our lives, but with a few slip ups. Some of the slip ups we've undone or trying to undo, e.g. freon based refrigeration, fossil fuels (a be it VERY slowly) and some questionable medical procedures. Other mistakes we're not willing to undo, either do to commercial reason or because we don't like being bored. We seem to be rather unwilling to undo things that hurt us mentally.

Things I really think we need to rollback include social media, which on paper seems like a good idea, but doesn't work well in practise. The same goes (highly) commercialized TV. The 24 hour news-cycle isn't providing any real value, but is still immensely harmful. You can just avoid those thing, but many people can't, they are mentally not equipped to do so. Even those of us who think that we're in control of our media consumption will often catch ourself slipping.

We've created a world that we can't mentally handle, but we're not willing to rollback the inventions that are clearly harmful, because they are profitable and we're bored. We can barely manage gambling, we not even trying to manage or just label media.

I think it's more than unwilling, we're straight up unable. Not in principle, but because it's a coordination problem.

Think of how many parents now want their kids not to have a smartphone or social media. There's genuine, well researched evidence that this would be good. But there's also real harm to kids who see all their friends with iPhones and Instagram. It might sound silly to us but it's definitely real feeling to the kids.

A lot of the parents who let their kids use smartphones and social media probably could be easily convinced that it's a bad idea, they just don't know. Or they don't know how bad it is, and so something else, like displaying status via a nice phone, they value more highly.

But until we can reach critical mass, and fight the (not insignificant, and quite intentional) momentum to use social media, it will be hard.

Why do you think it wouldn't work to roll back social media? It's only existed for 20-30 years. The world worked fine without it. We put men on the moon without it.
