I always thought it was some sort of Frank Lloyd Wright reference, because I didn't know anything else, but this fits the reference better.
I visited Arcosanti in 2013. Unfortunately it's an unfinished, incomplete project - Soleri's goal was to reach a population of 5,000 people, a number he thought it would make the community completely self-sustainable. I think it reached ~100-150 at its peak.
It is entirely possible that these traits of Soleri are at the root of the stagnation of Arcosanti
This was a huge problem. If there's any one thing which defines "what a city is", it's that it arises from a multiplicity of visions, not from a singular ideal. And Arcosanti needed multiple visions, because Soleri's vision was certainly incomplete. His understanding of economics, for example, was not just naive, but nonexistent.
Source: I lived at Arcosanti for 5 years in the mid 90s, and knew Paolo well.
Edit: but perhaps you're right, and there's some root psychological defect which manifests as both egotism and sexual abuse.
However much i like the visuals of solieris vision, concrete, hippie and brutalist architecture in general, i find the idea of life a city that cannot grow but inwards pretty grim.
Not enough, I'd guess, but you could afford basic water and food if you can sell something else at a high enough price.

Getting to self sustainability always suffers from bootstrap problems, and closed loop living systems of this sort, even at 5,000 people, would suffer from lack of domain expertise or specialized resources to be truly self sustainable. At least unless they either target a low technological level of life or pick the exact 5,000 people needed to keep things going.
That's not meant to be a criticism of this project. If anything the project has strong value in helping to understand roadblocks to small self-sustaining communities, while also contributing to the zeitgeist of fascinating, quirky niche communities that enhance our culture in valuable ways.
