The problem isn't the lack of laws, it's the lack of enforcement. Biden's FTC gave us a glimpse of what a working antitrust enforcer could look like, and it caused a bunch of influential billionaires to switch political allegiances.

There's no escaping the politics here. You can't enforce antitrust without hitting the billionaire class directly, and those people know how to influence American politics in their favor. Just look at what happened to the "click to cancel" rule post-Trump, something that is unambiguously pro-consumer and exactly the type of thing the FTC should be doing.
