Giving people freedom to do their jobs is how we got the Crowdstrike incident. Those rules and restrictions at a hospital are in place precisely because there are enough people who cannot be trusted with the freedom to do their jobs to make them unavoidable.
Your premise is highly debatable; I don't know anyone who determined Crowdstrike was the result of "freedom to do your job", but regardless the hospital rules are for regular operation, not black swan events like this.
