Especially with natural monopolies like infrastructure, there is no economic case to overbuild most power grids, water/sewer districts, Telecom infrastructure or natural gas networks regardless of regulation. The rare times you see overbuilding there is always a scheme involved, whether it's Comcast's recent edge outs to appear as though they aren't bleeding internet customers, or government money incentivising an overbuild cause the current ISP didn't document that they serve a set of addresses.
