So far the invention of metaphysics has not solve no problems yet. Therefore it is right to say metaphysics has not progess, and should be dismantled, by the logical postivist.
But metaphysics I think it serves to be something else then solving things,
I think it is to ask non-sensical questions, that are often laugh at and produce a beyond imagination and thinking together. Or so I believe.

I agree with your second statement. Metaphysics is the push behind scientific research and religious specualtion. Metaphysics IMO, is important if we are searching for truth and want to acquire knowledge. Here’s a metaphysical thought: is levitation a reality or figment of imagination? I’ve seen David Blaine demonstrate it on TV well its not live but judging from spectators reaction, I can see he is able to do it. I want expalnation of that phenomenon.
