Regardless of that (LBO's should be illegal anyway IMO) you can do lots of poison pill style things at the BoD and even union contract level to deincentivize that kind of jackwagon tomfoolery. But even that doesn't have to be an issue if you instead invested more of that burnback money into still needed infrastructure like better and more reliable IFE, truly redundant computer systems, every single gate at every single station having awesome air, resource staffing to handle the meltdown load demands instead of just the averages, etc.

Gates and Aircraft don't really count because you always have to have those. So quoting how many "billions" are spent on those while burning other billions doesn't mean balance has been achieved.

If the purpose is to get the money off the books so some corporate raider scum can't use it against us, there's still better ways to do that in many cases.
