>Why do regulations have to be in line with market economics in the first place?

Yeah, I think this is something a lot of folks overlook - regulations exist because society has decided its interests are better served by making folks play by a certain set of rules than by hitting peak market efficiency or whatever. Now you can argue that a given regulation is not the best way to achieve a societal goal (for instance that limits on cab numbers don't reduce congestion much) or that they have worse externalities (medallion systems squeezing out the little guy in favor of big companies that can afford 6-figure medallion prices) or that the lost efficiency isn't worth society's goals, but straight up saying that they're "inefficient" isn't a case for anything.
