The Einstein quote comes to mind:

"We can not solve our problems with the same level of thinking that created them."

There are a whole host of assumptions that your arguments rest on, from our ability to predict and control non-linear dynamic systems, to what we even mean when we say "cost" or "quality of life". It's great that you're optimistic, but I fear this is more of the same arrogance that got us into this mess in the first place.
