Using corporate externalities to trivialize individual contribution is utter nonsense, though. Coke does not make plastic bottles because they think it's fun. Big oil executives don't just fill big Scrooge McDuck swimming pools of the black stuff.
Individuals purchase products from companies, driving that demand. Then are absolutely unwilling to make even the tiniest, temporary sacrifices to demand those companies reduce those externalities.
Hell, half of these individuals don't even both to vote. That's straight-up the bare minimum participation trophy level of effort.
