Clearly it is! And anyway the canal system would not be used as a transport system for people getting from A to B. It would be for the transportation of goods.
Ok you can have a decent transport infrastructure- good luck when house prices rise and rent prices do.
Trust me, it'll be nowhere near London prices. For all our wonderful transport system I would much rather be paying cheaper prices for beer and mortgage
Apart from freight and family/friend/tourism journeys, nobody needs to go anywhere for business now. Just connect digitally. HS2 is a white elephant. It will be a century or more before it pays for itself. Maybe I'm wrong, If so who cares!! It's just my opinion.
