My conservative relatives are getting riled up about CBDCs and how the US government is going to pull a corralito (https://en.wikipedia.org/wiki/Corralito) with it. 

I don't think a CBDC makes a government more able to corralito us than the current digital system. Am I wrong?

Your relatives just need a boogie man to project their fears on. I like to think of it as a new hit song on the fear billboard. The news they consume will just play the top 100 hits and cycle through a list. Are CBDC’s bad? Arguably yes, but the hyperbolic reaction is just silly.
