I’m a permaculture designer and have run a small vegetable farm. I have visited Polyface twice and spoken personally with Joel Salatin both times. I’ve read several of his books. I think that Polyface shows up in this discussion very much on the side of the systemic safeguards the article recommends. His farm is full of systems and safeguards a great many things by design. He plans for every risk he can think of and adapts his system in response. He got the farm from his father and has largely transferred it to his son, and they have built a business training both interns and the interested public in their methods.
Sorry, I wasn't trying to claim that small businesses don't need any safeguards. For example, small businesses also need backups, they need TLS certificates, lots of industry-standard stuff. What they don't necessarily need are everything required by the checklists that are thousands of items long where every box must be checked to pass SOC 2, ISO 27001, FedRAMP, etc.
Safety measures ≠ world-dominating industrial scale.
