NGU is a financial instrument within the fiat economy.
If the supply chain demands fiat, then spending bitcoin simply creates demand for fiat.
That also means offramps are more important to the market than self custody, and so most people will be using a custodian.
Custodians can rehypothecate, and very few people will care, that's the end of the 21 million cap.
NGU = just another asset class.
Bitcoin as a new territory of freedom is where the opportunity lies, but practically no one is using it that way.
