You can dig up an alley and re-string from poles with little hassle. Digging up everyone's yard, replacing lines that might now be running under garages or driveways, and just generally having to operate in people's yard is a lot more work. Especially multiplied by tens or hundreds of thousands of homes. If you can just trench an alley and run fiber to the nodes then re-use the existing copper for the last 100m that's probably a huge cost savings.
