The government is not a business, but people can adapt, learn and re-purpose their skills. I think that the key, mistaken, assumption that you're making in your pushback is that general competence does not exist: people who are good at business are hyper-specialised for that environment and their skills will not carry over to governance. I think some people are really good at very general, cross-domain skills and should be put in positions to use their skills effectively.
