Yeah, it's hard for the boomers to get around the idea of something that is digital to have real value, even if it's purely backed by energy and mathematics.
I think Mallers had the best analogy about it, when he debated Schiff. If they say digital things have no value, ask them to delete every single photo/video from their phone and cloud storage. Then ask them again if the physical phone is where the value is, or the 1s & 0s contained within it.
