You should read this part as a summary of the differences between punk and solarpunk, not a treaty on mixing optimism and political struggle.
> It just has to be clear that we're not going to get there with business as usual.
That's the part I don't see in solarpunk currently. The social structure is glossed over, and the technical side looks very much like technological messianism. The transformation itself is rarely addressed. I honestly enjoy the aesthetic, but I would call it calming rather than tought-provoking, that doesn't really leave solid foundations for political action.
