Well, since they don't actually land the Private Jets in the desert but at regular airports, how could you police this?  The Masters of the Universe who travel around in these devices use them to go everywhere, so all they gotta do is say they were in the neighborhood for a bizness meeting and decided to drop in the conference before or after it.  They actually arrive in a limo, not the jet.  Maybe they come in by chopper, you could ban those.

Otherwise, most of the complaints could be made about any week long climate conference where people go and spend a week in some mega conference hotel that has the HVAC running full time burning copious FFs to control the climate inside the conference meeting rooms.  At least at Burning Man they aren't running any air conditioners.

The whole idea of setting up a temporary city in the middle of a desert is of course stupid, but certainly no more stupid than setting up a permanent one like Las Vegas or Phoenix.  If you're going to protestBurning Man, you need to also protest against all the people using single use plastics in Phoenix 365 days a year.  They put up a lot more than 100,000 tons of CO₂, which is just a drop in the bucket really.  You also need to subtract off all the FFs the attendees would have burned at home during the week they spent in a tent at burning man.  I bet most of them burn more FFs in a normal week at home than they do while stuck out in the desert all week, where they walk to all the exhibits.

I realize this is all symbolic of course, but really WTF cares about Burning Man anyhow?  Now, if they set up a big Picket Line and glued themselves to the pavement around the Port of  Los Angeles to protest against all the container ships unloading there, that would be meaningful.  I bet one container ship puts as much CO₂ up into the atmosphere in a day as Burning Man does in a week.  That's just ONE of the hundreds unloaded in a week, which are all stuffed to the gills with single use plastic packaging materials.  Burning Man is a Flea in the FF burning parade while the Godzillas exhale huge volumes of CO₂ daily with every breath of the industrial machine.
