I answered this question, this way a few months back: Which is where proper bidding time lines come into play and a set bidding order. There would be little gain in such a strategy, if you're spending your resources on keeping people off your roads you're also keeping away any profit from those roads. The pipelines of major interstate would be of the most value to a large corporation or even a large group of people or one wealthy individual.

The ability to expand or make new roads for competition becomes even greater strategy for better profits. Your argument is flawed when it comes to reality. Sure, you could buy the roads around my home, and you could set it so high that I could not travel on those roads. Others though would be less likely to travel on those roads too, as it makes no difference if they can reach my home.

We could even state that such auctioning off of neighborhood roads is unnecessary as a homesteading has already occurred by the residents of that area. Simple appropriation of such roads defaults to the homeowners because of a 9/10ths rule, everyone in the community at sometime paid something for the road maintenance & as such owns a fraction of 1% percent of the public property. Breaking down ownership to a block, more or less, provides probably the best way to treat high residential areas ownership. The act of dividing up public property to private owners is a tough proposition, yet it something that will come about in a total collapse and preparedness of handling of such matters should be of importance of any community & plans should be drawn up based on a 9/10ts rule. Simple appropriation to a defunct body doesn't get the job done. Further, for the roads that have not a homeowner, rather a homesteader on that land, those roads should be put up for auction if that land surrounding that road is not homesteaded; as such a land owner has not even homesteaded that property that he owns, can't very well state that he homesteaded that road. He can however, utilize that unused property as a competing road to that road that gets bought up.

However, if you think you can go around and bully such people than, you should also hope that being such an asshole doesn't come back and bite you in the ass as a I collude with your neighbors, that would know you're a dick and probably hate you anyway, from shutting off water(or gas) that extends to your home that crosses over their property.

To come back to the point, such tactics do not give you any economical advantages & only dampens your standings with the rest of the community.

tl;dr Homesteading is also a viable means to appropriate public road ways. . Actually, that is exactly how it should probably be divided up now that I gave it some thought. If there is no homesteader in the vicinity, than the road should be auctioned.
