Hadn’t thought to include limited natural resources in the analysis, but it is something I’ve been thinking about. Could put the kabosh on the whole notion of ‘post scarcity.’ But of course, to the extent that there is work to be done (and less combustible fuel may mean more humyn toil), doing so should not be a privilege. How to reconcile that with ‘voluntarism’ is tricky, but surely involuntary unemployment must somehow violate any meaningful understanding of voluntarism.
