What I am trying to say, is that to fight climate change lifestyle changes are required. To get those changes done in a demicratic fashion, you need to convince a majority of people to actually make those changes. Part of that is making them without the actual law, to show that it is possible.
Just take you as an example. You want I presume a combustionengine ban. However that ban would cause you massive problems, as you can not get to work or buy food without a car. I would say that, if true, those would be amazing arguments against such a ban. For me the argument is much easies, as I would do more or less fine with that law, as my lifestyle is already pretty low car.
Remember when we tried to get people to wear masks during the pandemic?
Remeber the US president refusing to wear a mask in public? Johnsons parties during covid? There was a lot of that bs.
The top 10% globally emit almost half of global emissions That group is also the one, which can afford the alternatives, like for example EVs.
You also ignore that actually living the change, is what builts up the alternatives. Lets take EVs as an example. Economies of scale bring down prices and more EVs means more reason to expand charging infrastructure. We can in fact see both of those in action. That kind of stuff also works socially. The more EVs are around, the more normal they become. It also lowers oil sales, which hurt oil companies, which makes them weaker.
Aligning you politics and your lifestyle, also makes you more effective politically. Somebody who rudes their bike in everyday life as trandport, will call for very different things, then somebody who only drives everywhere. That can just be knowing the worst parts in the cycling network. Also again, it makes it more believable, when you lobby for something, which makes your life better.
So I will continue to try to live a life, which aligns with my values, and not pretend I gave up all my agency to Wallstreet.
