If you apply the definition of debt as future value pulled forward, everything is debt.

I enjoy the philosophical logic, but no one defines debt this way.
Debt is value owed back to another known party.
All fiat is owed back to the entity that issued it.
The same dollar can be owed back to more than one party with fractional reserve banking.

Bitcoin and the vast majority of crypto isn't owed back to anyone.
It's a completely different system on a fundamental level.
Especially true considering the open source nature of it all.
