> If the cost of carbon is the cost to rip it out of the air then everything works out let them fly as much as they want

The "let people do whatever as long as someone else picks up the externalized costs" is exactly how we got to the situation where the US was exporting plastic waste to China only to realize we now have a microplastics clusterfuck in our hands. So you'll have to forgive me if I'm a bit skeptical about the assumption that carbon offsets work 100% efficiently by merely looking at the amount of money transferring hands.

We need to fix that problem - especially the apportionment of carbon output (both from physical goods and from things like bitcoin). Political capital is better spent on that than on creating trivial loopholes while charging MSF doctors a fortune because they fly a to a warzone dozen times a year
