Because "Make a website" (however more sophisticated the prompt might be) is not a path to knowing what to put on the website, what the personality of it should be, what the hierarchy of information should be, etc.

Sprinting to a finished-looking result at step 1 gives you the illusion that these decisions were considered, but even the casual observer quickly concludes that the page has 3000 words yet nothing to say.
