I think you misunderstood me, or had a soapbox you wanted to stand on. My claim was limited--non-gradual population drops are a negative thing. Basic income is a way of re-allocating the value produced. I'm for it. It won't solve the problems that come from sudden population contraction, which would be a separate additional problem to add to those you list. For example, when you have way more houses than people, what happens to real estate prices and most of your people's net worth? The real estate and construction industry? Rent? Empty restaurants with too few people? When your tax base is too small and can't easily pay to maintain your infrastructure (Arecibo?) what happens to it?
