Is this some sort of straw man against trying to stay within your CO2 Budget? I really don’t understand the aim of this comment.

It's a really dumb test. You can apply it to argue against reducing or stopping literally anything. My dead great grandfather uses no fentanyl and commits no murders. If we're not doing those, we're as good as dead!

well thank god for the US citizens then taking one for team earth <3

ill keep supporting my local politicians who take a private jet for 100 kilometer journey to advocate for co2 reductions

I think it’s along the lines of “premature optimization is the root of all evil”. These little micro optimizations take your attention and energy away from places that might be less visible and less enjoyable but more consequential.

Whoever responds "we need to stay within our CO2 budgets, otherwise we'll be in real trouble in 20 years" with "being a hippie and organizing your life around recycling" is really building up some sort of weird straw man and not really usefully engaging in solving the problem.
