It seems like if you are too good at playing the game people will want the government to slap you with things like anticompete / antitrust to try and give you a handicap since you are too good at being competitive.
It's like no one here ever heard what regulatory capture or lobby is. https://en.wikipedia.org/wiki/Regulatory_capture

What you're mentioning is both unjust and unproductive if the company grows thanks to satisfying customers.
It's also a recipe for disaster:
Trying to break down megacorporations usually ends up creating even bigger megacorporations. You try to do so, and what you end up with is lobby groups, even more powerful conglomerate/holdings well established somewhere they can do it with advantages over the regular Mom and Pop stores that don't have access to this level of economies of scale and so on.
