> Eminent ___domain is not cheap to use given the fair market value compensation and the almost guaranteed legal fights.

I don't understand what point you tried to make.

Fair market value is what you expect to pay anyway, and the point of eminent ___domain is not to fleece property owners.

Legal disputes are also not a problem, and quite expectable. It's part of the checks and balances of not having corrupt government officials just steal property to hand it over to the highest bidder.

The key factor is political will. Government officials need to fight to get this sort of project through, and be able to invest their time and effort to navigate political chicanery.
