Is There a Sweet Spot for Regulation?

Politicians are saying we need to stop these big companies because they're doing x or y or z, by breaking them up and so forth. I don't at first i don't think breaking them up is going to fix it. But more importantly, if they're doing something that is really not ok, then write a law tt restricts that very thing. And in case you're wondering where i get this inspiration from, guess who's trying to regulate aogrithms? China,. of all the places, which was completely unmanaged.
