> You're making a false equivalency between the State and other market actors.
This is a meaningless objection: no two things are exactly the same, but it can be useful to consider how they're similar.
> You may not be using the US government's services, but you're probably using your own government's.
Yes, and then I pay for them.
> Forcing a service on people (say the War on Drugs) and then demanding payment through taxation is different from competing in the market.
No it's not. Many companies take the money I paid for their service and use it in ways I don't like. I get far less say in their use of this money than I do in my country's government.
(My government doesn't have a monopoly on road building - I had to pay for the road up to my house - so I don't know what that refers to)
> You must follow things back to the origin.
Not really. While it may be interesting to find out the origin of certain rules and customs, it makes little difference to the way they are now.
> For a price, and then only to enter another country.
True, nothing in life is free; that's why it's a good general rule that poor people shouldn't pay taxes. But there are countries without governments and there are unclaimed territories around the world - they're just not very nice places to live.
