I'd like to challenge your definition of physicality. The components of Bitcoin have physical representations as the configuration of memory storage devices across the world and all the brains who recognize the data and concept of Bitcoin and its mechanics. Since matter can neither be created nor destroyed, the capacity of information in the world can neither be created or destroyed, just realized or unrealized.

Theoretically matter can be rearranged into worlds where our current consciousness is a random configuration of matter that can devolve at any second (https://en.wikipedia.org/wiki/Boltzmann_brain). The interesting thing about humans is our ability to search for and find relevant pieces of information that benefit us rather than having to enumerate the infinitely available possibilities in the style of The Library of Babel (https://en.wikipedia.org/wiki/The_Library_of_Babel)
