You ask:
Why theater can only be an entertaining place?
I would propose the radically opposite:
Theatre should be only and exclusively a place of entertainment - understood from origin: entertain late 15c., "to keep up, maintain, "from O.Fr. entretenir "to hold together, also to have a guest - to show hospitality.
