To my knowledge, all french highways and major railways are also already populated with fiber so you can just rent some point-to-point transit there from established operators without having to lay your own.

Good luck with this project keep us updated

I assume the former because the conversation was about USA in the first place. It is my understanding that US industry and law enforcement has exactly 0 respect for peace treaties with indigenous nations and their territorial sovereignty, especially when it comes to extracting natural resources.

However, it's good if local communities care for respecting other people's lands. If your fiber needs to cross private property or indigenous reservations, i'd recommend having an honest discussion with their residents. Maybe some would actually like to have good connection as a public service (as the Rhizomatica project has been building mobile phone and internet infrastructure for some communities in another part of the world) but would be hostile to private for-profits ignoring their needs.
