There are some in the industry (like Fun Spot, who are required to have inspections at all 3 of their locations anyway), who are in favor of state inspections. In fact, I'd argue only the largest operators are against them (and work to try and get states like California, Texas, NY, and PA, all of which have yearly inspection requirements led by a state department, changed o have changed to a similar system to have Florida has currently). I have heard executive brag about their attempts to "influence" state leaders to change their rules and regulations to make it easier for the parks to self regulate (although they've never convinced a state to go full Florida mode yet, at least in states where there's major parks).
It is not cut and dry, and in this case would literally impact the biggest parks because smaller parks are required to be state inspected in Florida anyway!
