I think it's because we're watching schizophrenia and a doc who feels it's just rich escapism.

Mental illness like schizophrenia are by definition a net negative, that’s why their disorders. It seems strange but people can be very different without mental problems or seem perfectly normal but have severe issues.

It’s why some but not all young children with imaginary friends can be considered fine. More strangely some adults have similar imaginary friends which they realize are mental constructs but they still enjoy interacting with them.
