Solarpunk sounds likely doomsday prepper shit

I don't know where else to put this. I'm sorry if it's in the wrong place and will move it if it's not appropriate here.

Every time I read anything from so-called solarpunks, it reads like slightly left of centre ravings of doomsday preppers. They seem to love many of the same fascist talking points. For example, individualism self-sufficiency , which sounds a lot like the frontier cowboy fantasies of right-wing nutters. They promote what essentially is subsistence farming, which is a terrible way to live. There's a reason this kind of shit leads to famine in developing countries. An almost enthusiastic fantasy surrounding primitism and the loss of technology. There are so many issues, I could go on. Unless I'm missing something (possible) I don't see much appealing about solarpunk because it seems to have a delusional nostalgia for the "good old days", much in the way conservativism does.

Is it really as crackpot as it sounds? If not, what am I missing?
