Lol! Doesn't make sense at all! Before Digital USD, China will bring in Digital Yuan and it seems that digital economy is inevitable because it's cheaper and easy to monitor. Digital currencies will greatly help the government to monitor their citizen's finances. So eventually all countries will slowly move to digital infrastructure.

However, these CBDCs will not be classified as a Defi at all! There is no way a government will allow that to happen because they will loose control over their own currencies. So don't daydream, please!
