On 1) -- yes, but that's just how it is: I love the thing I read recently like "If people would just." -- okay, you can stop there, because people will never "just." But it really doesn't matter; you engineer the best you can around that. My favorite go to example here is elevators. We have successfully safety-engineered elevators so well that any idiot can shove their hand in front of a two ton door and the result will be so harmless that it's a common practice now. Surely we can do that for CLICKING ON LINKS.

2) is harder, for sure. Great point.
