This is problematic though, isn't it?

It's effectively mass subsidization for bad behavior at the expense of people who are altruistic. I don't see how it can be a winning strategy in the long run.

For just a second, let's set aside our hopes and idealism, because I do realize how distasteful this world view may be.

If the best hope for the environment is that altruistic people suffer a disadvantage so that everyone (including defectors who don't want to help anyone and only help themselves) can win, how is that not a strong long term advantage for anti-social behavior?

"Great, don't take that plane ride, stop burning fossil fuels. More for me until we run out! I can even afford to have more kids because I don't care how impactful they are, while you responsibly go extinct."

Feels like a losing battle, and not a fun way to lose either. I suspect that we all know, despite our hopes, that eight billion people will not decide to collectively give up their own happiness for the betterment of billions of strangers they aren't related to.
