How about let's look at this with some common sense, OK? First of all, this LGBT gathering has been going on here for decades. There have been special permits and exceptions given in the past when applied for, such as for camping out on the beach. (Aside: this article doesn't mention whether the 'camping' exception was granted this year or not, but I doubt there are as many folks staying out there overnight as in the past, for the simple reason that the big overnight parties are no longer held out there, but are scattered in various venues on the beach and in town.)
Look, I'm all in favor of the Leave No Trace ordinance, having seen too many vacationers just walk away at the end of their stay and not have the common decency to even take down their tent poles-- they just leave them, sometimes along with coolers and other crap, until the junk either washes into the sea with the tide or until finally a county employee decides the people aren't coming back, and disposes of it. Meanwhile the crapola hinders turtle nesting and is an eyesore for the next people coming down to enjoy the beauty of our beaches.
BUT, in the case of this long-standing, VERY large, very concentrated gathering, which already ties up traffic on the east end in a huge way, to require these visitors -- who, after all, do not have a rental house with dunes right behind their encampment where they can drag stuff to overnight-- to require them to take down and remove their tents/canopies etc. each night and somehow get them all the way to their off-site hotels or condos, often off the island (and where, even then, are they supposed to stow them??) and return them the next day, would be totally impractical and unreasonable, not to mention even more disruptive of other traffic using the east end (e.g., Portofino or adjacent development residents/renters, or people wanting to drive 399 to and from Navarre Beach).
And then there are the many, many attendees who help keep the traffic/parking problem down by taking a taxi to and from the gathering area. Not practical to ask them to take all their stuff back and forth in taxis for two or three days.
Don't get me wrong; I do feel that they should all at least be required to dump their stuff in dumpsters when they leave for good, if they aren't taking it with them. That should partly be a function of education (signs? social media? whatever) and partly finding a way to spot the dumpsters on site ahead of time (not sure why/if this is not done -- maybe space? Maybe aesthetics for the visitors? Maybe tying up the equipment for several extra days? Dunno. Speculating).
And of course it should also be common decency when it comes to cleaning up after oneself. But the LGBT community has no patent on generational lack of decency. Just look to our own county day trippers if you want to see who leaves most of the crap on our beaches day in and day out.
