In countries that use the USD as their primary currency, the USD is the currency of the tax raising authority in that country. However the citizens do also pay a small tax to the USA from the use of the USD in the form of seigniorage, i.e. they still have to buy the dollars. For coins this is apparently around 45 cents per dollar. As for entitlement to territory, the only entitlement to territory that really counts is the ability to keep hold of it. If you want an anarchist utopia, you may have problems keeping it for any length of time unless you are fairly inaccessible or fairly martial. This isn't particularly fair, admittedly.
