Wait..are you suggesting tax something because reason A in order to raise money for thing B where A has absolutely no relation to B? This is why people hate liberals. Why do we need to arbitrarily tax things? Let me guess these are things you don't like or use so you have no problem with increasing taxes on them.

No, I'm suggesting that if activity A imposes some external cost on B, you can discourage A by the "proper" amount by taxing it even if the money doesn't go to B.

Would you mind cutting out that "this is why people hate liberals" nonsense? It's incredibly obnoxious.
