I don't know what the "live in" part is about, but you're being obtuse otherwise. Artists are cool and fine (and are themselves workers at least sometimes), the point is that, at least by the perception of some, solarpunk is overwhelmingly a playground utopia with no attention paid to the people responsible for its creation or maintenance.

I think the interest in the people who built the buildings themselves is slightly exaggerated, but when these buildings are such an object of focus, it does make sense to give a bit of attention to their construction as well, and there's always the option to depict more limited renovations of the kind that private citizens do often do with their own homes.
