We have a set limit for how much carbon can be released to hit the agreed on targets. Anything a person emits over this should be reduced.
Someone eating meat 3 meals a day and flying in a private jet, is using thousands of times over this level. The average person in a developing nation is using a fraction of this. Why should they stop emitting their fraction, when the jet setter uses their thousands over budget.
Stopping private jets is a tiny tiny tiny sacrifice for people. I for one have never used one, neither has anyone I know. We can safely ban them and only a few people will feel any impact, and it will be a pretty minor one, much less than thousands and thousands of people not having lighting or refrigeration.
