For example, low emission zones for cars - you have to have a new car to be able to drive in a low emission zone. So, who can afford it?
Cheap airplane tickets, make them more expensive - who will be able to afford to fly? Beef contaminates, make it more expensive, same result.
You can follow the logic from there.
It's actually a little concerning how your line of reasoning seems to follow the most dystopian path, can't you see any other way of it happening?
"Airplane tickets are too cheap" is a talking point of French politicians recently. It's likely they will do something about it.
The EU already has a law in place saying no more regular cars can be sold starting in 2035. Of course, with a nice exception for Ferraris.
These dystopian things are happening now, I'm not imagining things.
Banning them all would make my life difficult in many ways, but there would be some really huge upsides.
You can live in Mackinak and try out the no car lifestyle. Watch out for the crap and piss in the gutters. https://www.michigan.org/city/mackinac-island
I’m not the OP, but if I take one less flight, avoid a car trip and choose not to eat beef, the same has happened with no regulation change.
It doesn’t have to be all or nothing, small steps help and the OPs positive approach is very different to the ‘tax it’ approach you have described.
