I think that your confidence is a little too high on this one. It's very possible to paint yourself into a corner that no amount of magical economics "a solution to any problem will present itself if the price is right" thinking can get you out of. You sound like a politician making appeals of "smart people will work out the details of the impossible promises I'm making."
