I don't think it's the same question, because the dollar and bitcoin aren't currently linked by any official US monetary policy. That's the part that's tripping me up.

every time we see the 'exchange rate' of bitcoin go down that means people are 'selling it'... right?

why? i mean sure buying something with it i understand that that makes sense.
but selling it? isn't that the same question basically?

Saylor's Grand Strategy: Sell Dollars USDT & Recapitalize the Entire US on BTC

I definitely get why the US wants as much dollar demand as possible and how stable coins potentially help that. 

I’m unsure how much dollar demand there will be after the announcement of a policy that explicitly prints dollars in order to buy bitcoin. 

It’s pitched as front running Bitcoin’s eventual value, which makes sense on its own terms. However, why wouldn’t other nations skip the middle man and front run the US by buying bitcoin instead of stable coins?
