General Discussion

That is why economics has a concept called "externalities." The obvious conclusion is that economic costs are non-comprehensive, at best.

Even so, positive externalities are monetized quickly by whomever notices and can get up and running.

Negative externalities are ignored (see: Climate Change) or farmed out to the public sector. Either way, those costs are paid either through government programs, human suffering, or disasters of varying degrees.

So, in a sense we are already ignoring costs -those we don't like and make people rich. We simply ignore the economic impacts we don't like. That being the case, there is no reason we can't ignore the costs that we do like. And we should. The entire idea is antiquated and unnecessary.
