Hmm, you're arguing to attempt to get to a 'stage two civilization' per the kardashev scale, and while I agree there's all sorts of issues with attempting policy-level change I keep seeing a lot of energy/material/ecological blindness with such arguments to go beyond boundaries.

"since technology can make more use out of less material and energy by increasing efficiency or creating alternate methods of accomplishing the same tasks" - I keep thinking we're falling into the 'jevon's paradox' here without sufficient systemic accounting or feedbacks.
It's a worthy goal to at least attempt to complete our transition to a Type I civilization and begin work on Type II, the line is probably quite blurry since any type of space exploitation moves you towards II but is quite possible before completing I. I don't doubt the validity of Jevon's paradox but I think it's implications are not negative. From Wikipedia's article on it " increased the efficiency of coal use led to the increased consumption of coal in a wide range of industries" the key point there is that the increased consumption came from a wider application of the technology in areas where it was not able to be used before. This led to higher output and innovation in those industries which further accelerated the industrial revolution. A modern example would be Moore's law which has improved efficiency in transistor production, spreading the technology to almost every other industry resulting in further increases in efficiency and many revolutions and breakthroughs.
