I know this isn't the point of your thread, but on the topic of physical vs. metaphysical: Everything is physical, including metaphysical things. This should even be obvious. Even consciousness, from an Eastern spiritual perspective, is physical, it's just very subtle. To say that something can exist without any level of physicality, that's like saying something can exist without existing. At the essence of all things physicality doesn't necessarily need to imply locality, and arguably (though I would disagree) it doesn't necessarily need to imply temporality, either, but it is essential to any and all existence.
