> If I don't like Uber, I can... stop using Uber. What can I do if I don't like the service a state provides - can I opt out and stop paying? No, my only option is to flee - which the state will often try and prevent you doing anyway.

You can't evade a service like Uber either which does have an impact on the commons just like a Government does. You can avoid giving Uber your money but that isn't quite the same thing.
