Nothing more than it’s widely accepted

Well, what's wrong with Bitcoiners trying to make their currency widely accepted too?

that it’s backed by yet another widely accepted from of currency

(usually; gold)

Not the USD, which is the worlds most widely accepted currency.

This is all gross-oversimplification, I realize, and I don’t particularly want to get into the weeds on this topic, because it’s only of passing interest to me.

Yes, I agree that this is gross-oversimplification. But if you don't want to get into the weeds, why make a claim about something you don't understand and don't have interest in?
