That would be really dumb considering the themes of the show are technology and human behavior.
The whole point of westworld in this series was collecting data on people with their cowboy hats so they could learn to predict and perhaps even emulate people by re creating them. Something they showed us in season 2 with the top guy at Delos. But they couldnt get it down and the host version of the person would keep going insane. Then later expanded on in season 3 by showing a supercomputer using data of people to make the "perfect world" or at least stop it from collapsing.
If there is no westworld they never collected that data which makes season 2 and 3 complete horseshit.
