"The cost to society is pretty much incalculable" Even if we cannot put precise figures on externalities, that doesn't mean we can't improve market efficiency and societal outcomes by taxing them based on reasonable estimates. "and who is to say your vices shouldn't be taxed over mine?" I'm not talking about taxing vices (e.g. taxes on activities that do self-harm). I'm talking about taxing externalities. "Did you seriously just cite a fictional book as evidence to your point?" I didn't cite it as evidence. I used the context from the book as an example of a situation where taxes could help drive better outcomes.
