We shouldn’t be so angry that we think something as broad/simple as a marketplace has no use, and should not even be attempted, in creating a sustainable society worth living in.
It looks like you are conflating market economy and capitalism. These are two different concepts, and the first one predates the second by a few millenia.
So in the end the question was about capitalism but you argued in favor of market economy.

Maybe we should, but I'm not sure we can - because one (nuclear + desalination) acts as a disincentive to the other (actually chaning practice).
Also, building a nuclear reactor takes a lot of time (do we have it ?), changing agricultural practices can start right now and scale progressively.
... or maybe switch to a less water intensive form of agriculture ?
Edit : I mean, how sustaining a wasteful practice with a huge wasteful infrastructure is progress ?
Just to be sure this is sarcasm, right ?
Hey there. As a non-architect interested in self-built housing, I found the barefoot architect quite interesting. I see this book as grassroot, community oriented architecture and urban planification (on a small scale). Maybe you'll find some inspiration here?
Also, I don't know where you're from, but in some countries legislation makes it mandatory to have and architect review what you plan to build - maybe with your expertise and your ability to sign construction plans, you could assist self-builders in their projects?
Is it though ? Not saying it is inherently bad, but in itself it forces a market value on everything - which is a rather limited proxy to usage value. In that sense money in itself is not neutral, not "just a tool", as it shapes how exchanges are made in a society.
