Almost by definition you can't have competition for large networks, road, data, water, electricity, gas, anything that needs lots of effort to set up to serve everyone. All the competing networks are more specific, rail, air, or much more limiting, broadcast tv. Thus as there can be no competition the network itself should have public ownership, and then there can be competition of services run on top of that network. UPS vs FedEx; various companies that sell electricity/gas over someone else's network; ISPs that run on the phone network, etc.
