Very fun, up to the point you get ill and start wishing industrial society still existed to manufacture modern medicines.

Why not both?

In some cases micro-gassifier rocket heater/stoves (just because you can make one out of mud doesn't mean it's not high technology!) & coppicing and pollarding will make more sense. In other cases clean atomic power and induction heaters/stoves will be the way to go.

Some times willow bark tea, and sometimes morphine.

This is as realistic as peace in the Middle East by getting both sides to sit on a beach and sing kumbya

I mean, we will eventually live in harmony with Nature one way or another. Shall we cooperate consciously in the process of life and evolution, or let everything crash and burn and hope the survivors do better next time?
