I'm okay with Poll taxes if and only if they're a voluntary alternative to jury service and military service.

Re Excise, Adam Smith described the negative consequences of tariffs better than I can.

But popular perceptions aren't wrong. If you have the infrastructure to secure cross-border movements, you have the infrastructure to tax it.

And "unfairly" discouraging imports from places whose policies you can't influence isn't always a bad idea. China's recent ban on graphite exports harms every industrial nation except Russia. Because those paranoid preppers never trusted China enough to outsource strategic materials production in the first place.
