So in other words, you want the US to use taxpayer money to buy enough Bitcoin in order to manipulate the price of Bitcoin--in the same way the US has a strategic reserve of oil that they sell off when the price of gas gets too high.

A strategic reserve would give the US government the power to determine the price of Bitcoin. They could make the price go up by buying it, and make the price go down by selling it.

That's what you want? Seriously? Are you mad?
