I’m not even sure what point you’re trying to make, here, but the presented concept seems clearly false to me: It is entirely possible to create things by starting with a blank canvas and then adding things that seem like a good idea until the entire piece looks right or functions as one wants, or to start from some sort of default setting and tweak parameters until one finds a new set of parameters that are interesting, without planning out the end result ahead of time.
