The FCC just released an NPRM to speed up access to utility poles, which is pretty much the only regulatory hurdle Google Fiber ran into. One of the options being considered is allowing new attachers to do make ready work themselves, which is similar to the one touch make ready laws Google pushed for in places like Louisville (the current pole attachment process requires existing attachers to move their own lines instead of letting new attachers move other attachers' lines themselves).

Google is hardly a startup or a new entrant into the market. They had a huge operations revenue to cover the costs of deployment.

The fact that Google Fibre exists only reinforces the assessment that you must be this big to enter the ISP market in the USA.
