It is definitely possible, but only really worth it in a place that isn't served by an existing "good enough" solution - one great example of this is B4RN in the UK. The area they serve is mostly rural, and existing broadband provision is woeful due to long lines to cabinets, and then long lines from cabinets, or worse, long exchange-only lines. Because the area is rural, they got the farmers to help - they get a reduced cost service (which is necessary in the UK for farmers to fill in statutory declarations that are online only) in return for allowing the wayleave, and also gets them involved with helping to dig trenches for the fibre to be laid into. The community gets involved as well, with many people who already enjoy the service getting stuck in to help put stuff in the ground. It really is a remarkable story, but would never have happened on the scale it has if they had good enough service from OpenReach.
