Sounds a lot like rational-basis but for administrative rulemaking (vs laws). i.e. the lowest possible bar the courts can impose. All you need is a reason this would accomplish some valid goal - doesn't have to be a good reason, doesn't have to have any basis in fact, it certainly doesn't have to be one you agree with. Just, "can you give me a reason for this law".

So, the reason here is "promoting competition". No need to demonstrate that this rule actually does it (in fact it does not, but that doesn't matter).

Courts ain't gonna do shit on this, sorry.
