No it's not.
Nowhere in the article does it suggest that, nor is it being contemplated in any serious current policy proposals.
It's about having digital cash transactions handled directly via government ledgers rather than via private intermediaries like MasterCard and Visa and PayPal. Which has all sorts of benefits. After all, money is a public good -- why should digital money be handled exclusively by private corporations making a profit off of it?
If government is in charge of printing the physical money people use directly, it's pretty logically consistent for it also to be in charge of digital ledgers in some form as well. We don't let MasterCard and Visa print up their own hundred dollar bills, after all.
