Budget airline travel bag policies - time for a change in laws?

So usually I wind up on Spirit or similar once a year due to schedule issues or last minute changes. It happens, I prepare myself for it, I make the flight for <2 hours, it works.

In the last month I have been on multiple budget airlines. Ryanair, Spirit, Frontier, Europa. It was not pretty. I have seen multiple screaming and thrashing fights at the gates over baggage and was involved in a heated discussion myself.

It seems most of the fights are based over "does the baggage fit in the bin" and also "it fit on the way over here and they let me fly with it".

For example, my wife's Samsonite rollaboard, noted as within dimensions in the literature pre-purchase, was a few milimeters too tall (not affected by overstuffing) to fit in Ryanair's bin. Somehow that was fine on flight one, but a grevious error on flight two. This was solved by me getting a running start and slamming it into the bin (it worked barely).

But anybody who is on these airlines and perhaps watches youtube or such knows the airline gate fight is getting to be a problem. People are regularly sustaining assualt and battery. Both innocent passengers and airline employees.

Perhaps its time for a change in legislation that addresses such, and not just about punishments for starting a fight (which turns out idiots will do regardless of existing punishments like a no-fly list) but also changing business practices of budget airlines.

It's not sustainable.
