Of course, transitioning to such a system where currently all roads are owned by everyone else and simultaneously by no-one, would be a tricky thing to solve. Though it has been "solved" in certain parts. E.g. If you consider large gated communities. It's not a perfect example, but it does hint at the possibility of people coming together to solve a communal problem using communal funding, and individuals having the option to leave if they don't like it and don't want to consent.
It took me the longest time to reconcile a bunch of these things when it came to Libertarianism (or further). Eventually I did "get it" when I started thinking about how I would solve these problems in the absence of a state and only having access to the concepts of "private property" and "contracts". Having a state there, ready and ever-present to fix all our problems is a cushion/crutch when it comes to solving the problems that a community would have to deal with.
