I agree with the sentiment, but this is UX 101.

UX isn't about always letting the user do something as fast as possible--that's just cargo cult UX. UX is about reducing the obstacles between user-intent and computer action. We want the computer to carry out the user's intent.

Sometimes that means frictionless UI: if I'm changing a font size, I want direct manipulation, instant feedback, etc. But if I'm transferring money, I want to make sure there are no mistakes and sometimes that means friction: confirmation steps, etc.

Saying that friction is good is just as useless as saying that speed is good. The whole point of UX design is to know when it's good and when it's not.
