First, it's not my definition it is the definition of the most renown Austrian economists who popularized the field that Bitcoin maxis are ostensibly fanboys of (Menger, Mises, Rothbard, etc)

Monero is constantly transmitting value though space just fine especially where i matters (free markets AKA black markets). If it becomes a SoV is yet to be seen since as it's currently in the MoE phase which is a precursor to SoV.

Gold total supply was never "verifiable" (and still isnt), but it still became money for humanity for thousands of years.

Yes, lightning is also transmitting value through space in tinier amounts, but almost entirely through custodians which defeats the entire purpose of Bitcoin (removing trusted third parties). There is almost no reason to use Bitcoin over fiat if you are trusting third parties and asking permission anyway. Maybe you guys will fix it's UX deficiencies at some point, and proliferate self-custodial permissionless transactions, then you'll have a stronger argument.
