Could you possibly explain/reason why this must be, without using "by definition"? Many people in this thread agree with you on this, but I don't understand it

Could you possibly explain/reason why this must be, without using "by definition"?

Is the richness you describe in your comment implicitly constrained to that which exists physically perhaps?
