In reductionist terms the real underlying reason for market failure is regulatory capture.
As to utility poles, a large number of poles are owned by power companies who by and large do not offer retail broadband services, so even here you are barking up the wrong tree.
That being said, there are issues with utility poles which need to be addressed. Efforts such as one touch make ready and the like are needed on a national level.
I think by "ownership" they mean monopolization of the poles due to agreements with the local govt to provide service in return for monopoly rights.
The parent to my original post identified a problem, but misdiagnosed the root cause and prescribed an incorrect solution.
As noted above a lot of poles are owned by power companies that do not offer broadband service. Furthermore exclusive franchises have not been permitted for a good while anymore.
Anybody with the correct permits can secure space on poles. This isn’t the issue. Part of the problems is how costs are assigned and how timely work progresses.
Who owns the pole isn’t the big issue.
