This actually happens to a degree defined by a working court system. And to make that smaller takes not a very complex set of laws, but they should be enforced. While IRL people make new laws when the bad thing is covered by existing ones which it's hard to enforce. As if it will be different with a new more specific law.

So I'm hopeful that anti-monopoly institutions get their shit together. This doesn't have to be this way. It isn't this way always . ATnT has been split at some point. Standard Oil and so on.

Wheels of justice grind slowly etc. If they still do grind faster than more injustice emerges - then they work and eventually those who fuck around find out. Otherwise - well, otherwise it'll be some new civilization after the new middle ages, ha-ha.
