Most governments of the world are in debt that will never be repaid because the growth needed to repay it would need to be funded with more debt. For every dollar of growth it is costing several dollars of debt.
The inevitable collapse of the global Ponzi scheme is what is likely fuelling the growing number of states to seriously look at issuing their own shitcoins. Initially they will be held and traded by central banks, commercial banks and businesses to give the illusion of legitimacy. Eventually they will be forced upon the masses to use them as we head into a cashless society, the infrastructure will be put in place so that if you don't, you wont have access to an ever increasing supply of items and services. I think this is why we see these mixed signals around the world where they crack down on crypto and exchanges and in the same breath speak positively about blockchain and crypto.
