i think some dualisms imply that the geist/soul/psyche can exist without the body, yes, you can substitute it to uranium in a power plant though which then necessarily needs the body (graphic crayons) to get catalyzed, but those are only analogies, the mind doesn't have to be physical, it only has to be more than the straightforward continuity of the body (the physical brain), for instance if there is an assymetric relationship in the direction of information. In reality of course things are much more complicated (autonomous nervous system, sympathic system...) but i am skeptical of straight up eliminative materialism as consciousness is, in my mind, an emergent entity, so that it is not reducible to its parts, i think it's also counting animals short and oversimplifying them as automatons (which is a typical western attitude rooted ironically in the dualist tradition), but in the end, like most philosophy, it really is a question of definition of what counts as mind and what is physical
