Your analysis is backwards. There aren't special laws that "make it difficult for new companies to hang wires." The issue was not Google hanging its own wires, but Google contractors moving AT&T's wires in order to make space on the poles. Louisville passed special laws to enable one company to relocate another company's property on utility poles. I think those laws are a good idea, but its hard to blame AT&T for not…
While I absolutely agree with you, that setup would have been untenable. I had an ATT line hanging about 6 feet off the ground(in Louisville, pole neighborhood). Took ATT multiple calls and visits, a total process of about a month, to adjust that one line on one pole. Now imagine a citywide rollout.
I'm all for having a set of processes and procedures in place, especially for an entity as large as ATT, but even by the standards of telecos their internal workings are a Franz Kafka nightmare.
