There is too much of the factory floor in the game for it to be sold for a cheap price. If there is a low entry bar, then people have will not really appreciate that it contains so much in progress stuff. Then there will be a social backlash about the product, ending is unpleasantness because they just don't realize how much of a work in progress it is. You aren't spending $X for a game. You are spending $X to be able to see inside the creation process. These are entirely different things and have different expectations.
Another analogy is:
Would you spend $50 for a 30 minute coffee break with some guy named Chris? (If yes, send me a check).
Alternatively, would you spend $50 for a 30 minute coffeebreak with Arcen's lead designer Chris? Two massively different things, but literally the same experience.
