If you're building in a place with electricity, the main relevant property right holder is the utility that owns the poles and conduits (and a regime exists for getting access to those, though it could be improved). Siting things like fiber cabinets isn't as big a deal because hold-out property owners have little leverage. If one won't let you build a node on their property, just build it across the street, and run the fiber along the poles and conduits that are already there.

The real hurdles are cable franchise and zoning boards. When AT&T tried to build fiber in SF, it wasn't individual property owners that tried to stop it from building fiber cabinets--it was NIMBY's acting to get the city to stop development. When Verizon tried to build fiber in Baltimore, it wasn't property owners that stopped it; it was the city, which wouldn't give it a TV license.
