"Everything in economics is zero-sum because the resources on the plane are finite" is an unimaginative undergraduate-level position that adds nothing of substance to the discussion.

If you want to have a constructive conversation about pricing environmental externalities then by all means, but you need to drop this "I'm smarter than you" attitude if you want better reactions to your comments, especially if you're just going to aggressively post lukewarm takes and then insult people.
