There's nothing wrong with "playing with your own hypothesis-space" as you put it, but it's stupid to believe in something without any proof that it might be true.

It's fine to think "what if god created the universe" or "what if we're living inside a giant space beaver" or "what if there is another fundamental force responsible for consciousness that we can't measure" but unless you actually have some evidence or reasoning that points in that direction, they are all stupid theories compared to materialism which actually fits into the current scientific world view pretty well.
