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?

I think the main concern (one that I share, frankly) is that the government will utilize the "programmable money" features of CBDCs to enact a lot of invasive practices upon people. Just the idea of those in govt having such an insanely powerful weapon to potentially wield scares the crap out of me, TBH.
