The best we can do is to give it time to prove them wrong, they will face reality. The
piece of eight, considered as the currency used by maritime piracy, was finally used internationally by colonies. If I'm correct even the US dollar comes from it, hence the name 'dollar'.
In the beginning, they said Btc is a gadget but now it can challenge institutions they started to see it differently. A problem is Bitcoin is misunderstood from the mass, but it can change the whole economy, it's only a matter to change the mentalities. People believe in capitalism, Bitcoin can make them believe in humanity.
From "In God, we trust" they will change to "In code, we trust" and the media outlet will follow the trend.
Yes, at the very least the $ comes from the s in PS (from Pesos), and lets not forget those coins were made of actual precious metals (ie. Gold). It probably didn't help that the "golden" age of piracy coincided with the peak of the Spanish empire, looting the Americas and establishing colonies worldwide, until they were eclipsed by the British.
Piece of eight was an interesting name used by English speakers, that's not its name in Spanish.
If anything the USD should be the current preferred money by criminals, since its more or less accepted anywhere, and the farther you use it from the USA (as in diplomatic relations, not physical distance) the less checks origin of funds will have.
I agree with "In code with trust". The USD has that God phrase, however the few humans that control can destroy it. As long as they keep that power, they will keep everyone hostage. Its like they using God as scapegoat for any of their wrongdoings.
Alternative is that longer phrase in that bitcoin 3d rendering: "In cryptography we trust". Well officially the word should be "Trustless" but that needs explaining. "Its a coin that no gov, bank, group or individual can destroy, get it?"
