Instead of asking government to have no-fly list, what doesn't each airline have its own list? They are private businesses and should be able to decide their customers, just like customers can refuse to do business with certain companies.
If there are privacy issues then they could just share a list of hashes and if someone's legal name hashes to something on the list then you deny them.
Also a hash doesn't provide privacy in itself. It just make enumerating people in the database more difficult.
1. People getting rowdy on planes recently is probably due to masking requirements
2. Airplanes have very efficient ventilation
3. Omicron is harmless to most people
4. Most people are vaccinated and protected against serious disease (Delta being the threat here, which has almost disappeared completely)
Simply remove the mask mandates and the problem will go away by itself (or at least return to normal).
They do.
