The solution to this has not changed. Public spaces are not public because they are not owned by anyone – they are public because they are owned by public entities. You can do that with computers and infrastructure just as much as you can do that with land and buildings. The one difference is that for land you can actually be there, whereas on the internet you will probably go through some privately owned infrastructure. The simple solution to that is encryption, the thorough solution is government regulation.
