I like
this John Green quote a lot:
You should pay taxes on services that you don't use because you have the means and others do not.
You should pay taxes on services that you don't use because someday you might need those services and you want them to still be around then.
You should pay taxes on services that you don't use because you don't want to live in a country with a bunch of stupid people.
If you want to go be a hermit in the woods and never talk to anybody you're welcome to do that. The rest of us will stay over here in our civilization and support one another. We've been doing it since the time of cavemen and it seems to work pretty well.
