All road services could be paid on a voluntary basis. If you don't pay, you don't use.

With Bitcoin, the exact money you paid for road service could be shown as to which part of the road it was applied to, and in joint with which other Bitcoin money for that section of roadway if necessary.

Rights of way do not necessarily be needed to be proved up. They can be wilderness-like trails that are trodden down by the people who use them. People who didn't pay for the roads could use the rights of way. The roads would be elsewhere, purchased by the people who used them.

No tax necessary. Rather, product/service and purchase, with an exact showing of what you purchased.

All government could be set up this way. Taxes are not necessary.
