It is the case that introducing something with a new name is really hard. This is exactly what Tether is trying to do:

Scudo, a new unit of account for Tether Gold (XAU₮), designed to bring back gold as a means of payment, accessible to everyone, as global gold interest and prices reach their highest levels on record.

Here's their rationale:

The challenge for many individuals is not belief in gold’s value, but practicality. XAU₮ already made physical gold digital, a groundbreaking and necessary step in a world fully connected by the Internet, where the economy moves at the speed of light. Tether has also released a technology layer, called WDK, that allows any developer, company, or AI agent to easily build, deploy, and distribute self-custodial wallets that function on any device and operating system and support XAU₮, as well as other companies’ stablecoins, alongside Bitcoin.

Yet a final hurdle was left to make gold truly usable by people in their day-to-day lives. Transacting or pricing goods in fractions of an ounce often requires working with long decimal values, which can be unintuitive and difficult to use in real-world contexts.

Scudo addresses this by introducing a simpler unit of account, similar to how smaller denominations have historically made currencies usable as money rather than abstract stores of value. For people familiar with Bitcoin, this approach can be compared to the “Satoshi” unit of account to solve the same problem.

I don't think Scudos are going to catch on, but Tether is pretty good at catching and surfing a wave, so who knows where this is headed.
