Why are there no multiplayer modes for turn base RPGs?

Hearthstone is there for you. Basically it's the same thing except 3d characters.

I'm not sure a card game is the same thing as a turn based rpg....... it's not an rpg for a start.

Hearthstone plays very differently to a theoretical multiplayer final fantasy or persona.
