I'm not sure of what use it is to believe in "a divine play of illusion" or how you even define such a thing. But you cannot build cars & airplanes & skyscrapers in a subjective world. Again, our inability to perfectly determine every detail of our objective reality doesn't make it any less objective. I do agree that the divide between perspectives is a primary source of social conflict, & people could be divided & both be equally wrong, but the feelings of helplessness & anxiousness when it comes to interacting with the world is a good sign that you are wrong.
