Everyone benefits from defense, roads, and so forth, so everyone should contribute.

No, not everyone. What about the millions of us expatriate Americans? Why must we pay for infrastructure and services from which we do not benefit...on top of paying taxes in the countries in which we are resident?

Do you work for a US company? If so, you benefit, albeit indirectly. Are you in a country that could be hostile to the US? Then if you have problems, I believe the US would bail you out. It's been done before. Yes, you might not drive on the roads all the time, but where do you drive when you visit the US?
