Good on Mrs Thomas!
Systems actually need some redundancy (unprofitable bus lines, public telephones, relatively inefficient but local farming) to give them resilience when things go wrong, as they are going to increasingly do while we continue to degrade our environment. The current crisis with the cost of food is largely due to excessive optimisation, resulting in a food chain that is very vulnerable to shocks such as the war in Ukraine. I've always been concerned about the lack of effort by the Japanese and British governments to make their countries more self-sufficient because it's less hassle to import stuff cheaply from overseas.
