Yes, Bitcoin mining consumes real-world energy, and that process ties it to physics. But electricity use alone doesn’t make something a physical element. A YouTube video also consumes electricity to be streamed - does that make it an element?

Bitcoin has no atomic mass, no molecular interactions, and no place on the periodic table. It’s a digital protocol, not a chemical substance. To call it a “digital element” is poetic, maybe even metaphorically compelling - but scientifically, it’s just incorrect.
