I agree. I am merely answering how the government would acquire BitCoin in the absence of any other value they could provide. The answer is how they always do, armed robbery.

I like Bitcoin, it is the best we have, but the best we have isn't very good. It can't natively handle the transaction volume and fees make reconciling tier 2 technologies, like lightning, back to the main chain difficult.

So yes I, think Catholics should support sound money in general and perhaps support further Bitcoin development, but because it is currently unworkable for people's day to day I wouldn't make it a moral imperative.
