Going back to your minimization of support requests comment, if your mom is unable to delete a file (like when SIP is enabled) she won't make a superfluous support request as she was prevented from making the error. As computers continue to be used as appliances, we should expect similar controls over the device to be deployed to minimize the harm a user can cause. This in turn leads to loss of agency by the specialist. Most people can understand the failure modes associated with microwaving metal and such (or if not, it can be a relatively cheap or expensive lesson). But that underscores the commoditization I was pointing at. The dangers of general computing devices can't be captured in simple aphorisms like "don't leave it on with a vessel that lacks contents" for a stove or "don't put metal inside" for a microwave. The warnings that accompany a computer would comprise encyclopedic volumes to encapsulate all the things that could go wrong, like "don't install software from someone you don't know on a computer through which you access your banking." There are so many instance like that it's unbelievable. Few other devices are so interconnected to so many aspects of our lives. The general nature simply lacks the guardrails and controls of a special-purpose appliance. Put another way, can you imagine the reduction in request volume from your mother if she had a special device for reading the news, and another for banking, and another for shopping? This is the rationale. I don't agree with it but convenience seems to trump everything else.
