Opening and closing of roads
Yes, it's a costly process, but it can be done.
Where I live, the power co. had decided to move the supply cables from masts to ducts in the ground. Since they had the diggers out and the roads open anyway, they put down empty tubes as well, and everyone in the village got a letter asking "Sir, in preparation for FTTH, should we lay down a tube from the road to the foundation of your house free of charge?". Sure, go right ahead. So they did.
Later, the power cos established a joint venture service provider, and to all the households where they had laid down tubes to the foundation, they now offered free installation of the fibre and the terminal gear if you subscribed to the service. Which I had anticipated, so I got 30/30 Mbit/s internet (or better - it's usually at 37/34) on top of a bunch of TV channels and telephone. And I saved on the overall monthly fee.
Sure, the fibres have a life span of 30 years, but they are in tubes, so no need to dig up the roads and pavements when the time comes.
