There is probably a version of this that works. I know that some orgs have tried something sort of like this. One problem with “hire contractors who aren’t value-aligned to do various things” is that you then have to manage those people (whether they’re value-aligned or not). This is getting outside the scope of your original question, but I think people underestimate how much it can drag on an organization to hire new people without thinking hard about their onboarding. If you have a very well-defined task, with a clear deliverable, then it can make sense to contract it out. But if you just have a problem and need help, often bringing on a new person to solve that will make things worse in the long run.
