Metaphysical is a concept created by a mind, we have no reason to think there is anything metaphysical in the first place. It needs to be demonstrated that there is such thing as "metaphysical", as well as "essence" and other similar terms, before it can even be considered as a reasonable position to hold. We can debate about it, philosophize about it, but holding any positive or firm beliefs about the existence of anything metaphysical would be illogical until it can be demonstrated to have substance or standing as a legitimate part of our reality.
