A better solution would be to have the "last mile" owned by the people who own properties, but that may be nit picking. And I think that's probably how things would have eventually developed without government intervention.
Now, I think that in reality, power companies (in the US, at least) almost always are regulatory monopolies, i.e., government-granted ones. But, because of the "last mile" solution, they don't _need_ to be.
In summary, I feel like my point that natural monopolies don't exist is still supported.
When a corporation thinks it can make money by suing municipalities that form broadband networks, they do so. Like in Lafayette.
You can't (logically) use one abuse of government power to justify other government power that counteracts it, which seems to be your argument.
In the example you gave, the abuse is being able to win invalid lawsuits, and that is being used to justify government regulation of arbitrary industries (telco, in this specific case).
Better to just make it so you can't win invalid lawsuits.
Because the cable companies and the ISPs and the media companies are largely owned by the same people, and collude monopolistically.
They do collude monopolistically: the telcos have government-granted regulatory monopolies.
deregulation achieved through the Telecommunications Act of 1996.
Given that the telco industry is 100% made up of government-granted regulatory monopolies, this act clearly did not implement deregulation.
