I think web3 could be solar punk compared to the current "web2". It allows for the possibility of smaller internets separate from "the internet" which could be just small webpages on raspberry pis. This would be "solar punk" since even me posting this pointless comment on an obscure forum is involving dozens of computers now and many more in the future as it's data mined (modern day problem, ideally it's resolved soon)
Yeah this could be built (and has been many times) using non-block chain tech, but if you wanted to ensure authenticity of any data you'd most likely need a blockchain - which might be nice if the "solar punk" thought experiment ever had to deal with any adversary
Are semi-automatic 3d printed guns legal in the US?
