A more accurate description would be that starlink will become the trunk, and possibly the service. Local cell services will own the poles but will essentially provide access for starlink customers. It's not a bad business idea, actually. People pay $30-40 a line for starlink cell service, starlink provides the big pipes so to speak and splits the bill with the local companies that put up the last mile towers.

In rural areas you can put up isolated 5G towers that have their own dish connection to starlink, no need to string a line to the towers anymore...
