Well if you put down your own wires to a new place you have a monoply. Of course if regulation requres you to share it then you dont. I think the root problem is that there never was a competiitive build up. You could easly imagen many diffrent companys starting out locally, say in big citys, and then to add more and more people, eventuall, you will get competution that way. These companys will soon find it profutable to rent out there wires to higher levels.

But non of this works if you have one company or the state build up a network and only then you start competition. Some people ignore the diffrence between free markets and privatisation/monopoly deregulation. This is the problem we are facing in tons of places. Free market get a bad wrap because privatisation often produces bad results.

Solving this problem now is really hard. One solution is that you just have the government build all the wires and rent them out low level to companys. Another is to deregulate completly and hope after some dark times market pulls threw. Another is to start doing fine grained regulation of every aspect.

I am very sceptical about government regulation that involve things lime you are suggesting, regulatory capture and the revolving door are a real problem if your regulation is to technical.

I dont have the solution, economiclly speaking all of these are very suboptimal.
