A lot of those pictures seem to be due to limitations in the technology they were using, not limitations of regulation... however, to address your question- if society decided to grant someone a monopoly, it should be to the government, not a private entity. So, for example, if society decided we only wanted one set of fiber cables ran throughout the city, they would decide that the city would run them, and then lease access (using VLANS or similar tech) to any service provider that wants to use them.
