That's all well and good. Let's say it works like that. And so the state only taxes those individuals consenting to the tax, and only provides services to those being taxed.
Fine.
What happens when you leave your property and drive on the road paid for by the taxpayers?
That would be trespass if I don't have permission. If I must pay a toll or some other fee for the use of some property that isn't mine, then I must decide if it is in my best interests to do so. It's not so unlike me wanting access to your house and you deny me unless I provide something in exchange.
In the context you use the word 'taxpayer', I could substitute the word shareholder, affiliate, member or associate.
