But that rebellion is from a stimulus of some kind. It's a subculture in rebellion from disenfranchisement, war, fascism, or what-have-you. There is anger and lots of other negative emotions.
This vision is too bland and perfect to be 'punk'. 'Avant garde' is a better term, since that is used to describe things 'rebelling' against the current aesthetic. 'Solavant Garde' doesn't have the same ring to it though.
The "what-have-you" in this case is the stronghold that capitalism and tragedy-of-the-commons has on urban society and our way of life. Of course, capitalism could produce such neigborhoods, at least on a small scale, simply because affluent folks will pay for it. But the ethos of solarpunk is to create these environments by taking matters into our own hands. Perhaps a decent analogy from the punk world is magazines versus fanzines.
I don't know, that argument isn't super compelling. It kind of reminds me of that one marketer at SXSW a while back that wanted the whole conference hall to have "idea sex" as some weird way of framing brainstorming or innovating.
Like if yall want to have your utopic fantasies then cool, but if you want to use the punk name there needs to be some raw grit
Besides... light has no meaning without dark to contrast it
Your idea of what is punk sounds like the mass-marketing by malcolm mclaren. Consider a band like the Buzzcocks, all around friendly looking blokes but they pressed up their own 7" singles, that is the true spirit of punk.
