If an engineer or machinist used to working with SI tools goes to work somewhere using metric measurements, perhaps building equipment for space travel...
Oh wait.
Obviously, doctors can get things done under less than ideal circumstances. I'm sure every TV show has had an episode of someone doing an in-field tracheotomy with a swiss army knife and a biro cap.
A license is not necessary for a Linux admin to work (in general). Screwing up a service file isn't on average going to result in the CEO of his company having a meeting with the company's attorneys and practice review boards to determine how much to pay the victim of his edits.
Worst case based on negligence (maybe taking all the zones down for a DNS provider), the admin loses his or her job.
You're comparing something minor with something that has both a high risk of serious damage or death (throw the statistical average value of life in here) plus an environment (especially in the USA) where attorneys advertise on bloody public buses for people who were "harmed" by a doctor, and there's a lot of ass covering with best practice behavior.
The human body is not a car (there's the metric/SI thing again). Things are bigger, smaller, in a slightly different location, softer, harder, or any of a million other combinations of complications that make it safer to use appropriate customized equipment.
