Maybe a dumb question, but what does "banning private jets" actually mean? Do we ban the actual planes themselves, as in, crack down on plane manufacturers to somehow restrict them from building small passenger capacity jet planes? And if so, what minimal capacity should be the threshold? Or do we ban private companies and individuals from flying jet planes under said hypothetical capacity? Another possibility might be to ban non-scheduled flights using jet planes.

In any case, who would have the authority to enforce this internationally, ICAO I guess? It does not appear like something they would even consider, their efforts being targeted towards implementing CORSIA (Carbon Offsetting and Reduction Scheme for International Aviation) instead.

Now to go even further, let's hypothesize that private jets are banned. What about non jet planes, as in props or turbo-props engines? Perfomance in terms of speed can be close to jet planes. Take for example the Piaggio Avanti EVO, which can reach around 740 km/h. While its fuel consumption is notably lower than similar jet planes, it's still higher per passenger than commercial flights. We can imagine a strong market demand for them will appear, to replace the banned model range. So should non jet private planes be banned as well? Even models like Cessna 172 and such?

Interestingly, I made a coding challenge for this exact problem a few years ago. You can find it on the Code Golf StackExchange website: https://codegolf.stackexchange.com/questions/26858/guess-the.... The challenge is named after the Lingo TV show which used the concept repopularized by Wordle. Lingo itself took inspiration from a 1955 paper game named Jotto. Regarding strategies used in the challenge, the best performing solution was an adaptation of a Mastermind solver.
