I hesitated before linking that specific statute because I suspected someone would parse it as you have. Not a bad thing, just distracts from the larger point that the US government currently has tools (of which Robinson-Patman is only one) to prevent & reverse the extreme consolidation that harms every American.

In the context of this article -- we may not need a new ban specific to preventing private equity from owning medical practices. We could simply enforce existing laws around e.g. market consolidation, consumer harm, etc.

Adding a new law to also be ignored seems silly.
