That's the problem with blanket regulations. You can't treat all fisheries the same, because they're different. Flatheads especially can put a hurting of other fish population.As an example on the morning of July 4th, I was fishing near a boat ramp at Cataract and an older guy set up near us on the bank. He caught probably a half dozen channel cats that couldn't have been a foot long and kept every one of them.
As for me, I agree a good keeper size is in that 14"-20"ish range. IMO there's a point were they don't taste as good and have more fat on them.
In general, I would prefer to see a daily limit vs a minimum size regulation. Over the years I've seen people get on the bite and would just keep feeling them in an tossing the fish in a Rubber maid tote. They wouldn't stop until it was full or the fish quit biting. I'm certainly not an expert, but I can see where that can take a toll. Especially on smaller fisheries.
