While there is no guarantee, think of it as a psychoanalyzing guess, if an idol has a unique or interesting stage name people will remember them or will have them imprinted in their heads. Which for low tier groups wanting to make it is a big thing.
So assuming there is no legal repercussion for making up your own stage name(I mean if RM can name himself rap monster anyone should be allowed to name themselves anything hehehe) , why don't more idols do it?
