This is how it used to be. When you bought a computer you got a full circuit diagram with it so you could understand how it works. All appliances were like this, and some still are, but the fancier it is the less likely.

There's no reason we can't mandate this even if our circuit boards and physical mechanisms are more complicated. It's clearly a net benefit for society.
