with respect to access private land, when the infrastructure was first installed there would have been an agreement for ongoing access even when the ownership of the land changes, and in many cases compensation could be a one off payment or a rental arrangement that carries forward. Infrastructure providing services on domestic property tends to have no cost or rental as it would have been written into the original contract to provide service, so replacing, or adding to an existing route is not a real problem, ie a cable run along the front of a row of shops etc...
With respect to cell sites, before 4g was rolled out most that were not feed by radio/microwave had an 8meg fibre system ( 4 times 2m channels) some a 34m ( 16 times 2m ) or even some with SDH nodes. With the roll out of 4g much of this was replaced with 10m 100m or 1g Backhaul some even 10g depending on the site .
So for a new network there is a lot of legal things to contend with, some ongoing costs, permits to dig the roads up, not to mention a workforce to do the duct laying, many companies are tied up with that sort of work for existing providers of telecoms, power, gas, water, so you would have to be considering having your own workforce and equipment to get the job done. Big task...
