I would happily pay a one time cost of $255 to run fiber to my house. I'd even be willing to pay $500 to run fiber to my house. Sadly around here if I want fiber to my house, even assuming I could find an ISP willing to run it, it would probably cost me upwards of $2000 to have it run, and probably significantly more than that. That's also not counting the cost of actually getting service, that's just the "installation fee" to have it run.
He said per person, not per household - not the same unless you're living alone. Also this doesn't make your internet free you have to pay for the service on top of that.
And believe it or not a lot of people don't care about having fiber internet available.
Once installed, fiber optic lines become long term infrastructure, and will be used for decades. With those time scales in mind, the line installation cost is reasonable even after accounting for market penetration and occupancy rates.
