I don't think that is a viable strategy, honestly. Antitrust regulation doesn't really punish anyone for misbehaving (geez this billionaire just got his company broken up, what a terrible thing we have done to him that will surely prevent someone from trying to merge something else) and doesn't address the crucial issue of emergent social inequality. It's a stopgap at best.
