@hanscees @datarama It is definitely not the first time I hear this ideas and arguments. It even may be the direction in which the events will take turn... just like Roman empire en-masse turned to Christianity, after first prosecuting it heavily...

What I am saying, that things like Tobin tax change don't magically optimize the consumption.

As for flying, the European tax cuts for airlines are ridiculous, but everybody is silent, because the voters won't vote for more expensive holidays.. but still, the total amount of consumption would not change. The money flows would change, but unless you totally restrict access to certain resource, the resource is going to be consumed.

Less private jets and more people flying to cheap holiday would be nice.. but the environmental impact is not social impact. Environmental impact It would be the same. And it is extremely unpopular opinion, because, no one really wants less consumption: people on right blame people, who supposedly don't work, so there could be more consumption, people on left blame inequality of consumption, but still want total amount of consumption to rise.

There is no easy way out. Of course, some solutions are easy: like do not force everyone to use AI, with its ridiculous energy consumption, or so.
