OK, fair enough. If we have to build and do all those things, what is it that we should STOP doing, buying, investing in? There is only so much time, capital, skill, energy (both literal energy and human willpower). What can we sacrifice? Commuting to work in droves? MacMansions? Travel for pleasure? Sporting events, concerts, and mega payments to celebrities? Buying new car every 5 years? Luxury cars? Infrastructure hungry suburbia’s and exurbia’s? Who will take a stab at this question?
Wealth isn't a zero-sum game. People in the first half of the 20th century didn't give up anything to develop electricity, automobiles, air travel, etc. But if our current regulations and institutions existed back then, we'd have missed out on many technologies.
Heck if aspirin were invented today, it's unlikely it would be approved by the FDA. Even if it was, it would be prescription-only. And if caffeine were invented today, the FDA would ban it and the DEA would find and arrest anyone manufacturing or using it.
