I wonder what the proportion of Parisians who would support this policy would be. It would not surprise me if 41% of the French population has taken fewer than 5 flights in their life, and that the proportion of Americans would be similar. The problem with these types of policies (restrictions or even just taxes on meat consumption, light bulb usage, or overall carbon output) is not just that they become unpopular when actually implemented, it leads to "solution aversion". The solitons to a problem become so detrimental that some people then convince themselves that the problem does not even exist.
