Walkable cities are very much a goal, so if you can stand them now, you'd probably be able to survive them even if the most ambitious solarpunk ideals were made manifest.

It's probably important to note that those ideals are just that - goals we strive for and proposed solutions for existing problems. But realistically we'll be lucky if we can keep the planet marginally habitable and prevent some extinctions. There's not much risk of suddenly being transported to a setting from a solarpunk novel.

And there'll still be apartment buildings and office jobs even in some Ecotopia-type truly solarpunk society

Edit to add: there are also plenty of ways to contribute to a more solarpunk world without getting anywhere near a farm or forest. I fix up ewaste laptops and refinish furniture and give them away to my neighbors. That's tangential at best to sustainable ecology or rewilding or the other things you might think of as solarpunk, but it reduces waste and it helps build community, and it can all be done indoors.
