If you ask me, I will say they are not and the will not. Let's start with Ripple network and banking partnerships that has happened over and over and yet they were just public talk, deep down they didn't use it and they never used it, some companies and government has announce to have even build independent blockchain to track many things but they were abandoned, probably they didn't have funding and were all abandoned, no developments later.

However, the government is interested in the value that is inside the blockchain. Look at the US election, all of them are begging for funding, begging crypto people to give them their coins so they can sell and fund their elections. Just some hours ago, Ripple CEO donated $1m to Kamala for her elections, and more are coming individually. These are the only thing the government understand, money and money and that's all, they don't don't understand any language than money.
