I think I understand what you are trying to get at.
Slight caution on the “more important” belief and trust.
It’s an accidental attribute of money, admits of more or less.
In the case of bitcoin as money, it removes both.
I don’t believe in bitcoin, there is no trust in the network.
When we exchange btc for goods and services, that’s real value 4 real value.
Perhaps you are right to say it’s more important when examining fiat, a specific kind of money, but when addressing money as a genus, general
category, the statement doesn’t hold.
