One solarpunk consideration that factored into my desire to buy a house is the ability to put in solar, passive underground heat collection, rainwater collection, and high-cost luxury perennials like fruit trees and berry bushes. These add about $700 of value to me a month, with startup costs breaking even within a few years. It's not fully replacing any category, just taking the edge off. I was unable to do any of these in a tiny apartment. I could comfortably reduce my consumption to nearly fully replace heat, water, and power. Food is the hard one.
There's something very powerful about knowing you are producing something real on your land. I'm not a nut about it, just like to see my property using the sun and rain.
