Earlier quoted context omitted.
Huh? What hypothetical car has the option to use your road or use the public road, but wasn't provided to you as a potential customer by the public road? Agreed, when a public road provides your customer, it's hard to win that competition. But again: you can just build your roads away from public roads, find your own customers, and then you don't need to compete with them.
>but wasn't provided to you as a potential customer by the public road? Mine, where I live the roads for miles and miles are all private with public easements and are privately funded. Of course by your definition that would make the public road illegitimate, because it has unfairly poached a private road user (not sure I agree with that).
Separately, how do you handle it when a neighbor decides to neglect their portion of a road?
Not sure what the illegitimacy point is about.
