Pinned straw:
Most of this article was the usual incorrect/misunderstood, tropes of why Bitcoin will not succeed (energy use, transaction speed, layering centralisation, etc).
However, I think worth persevering through for one good observation; The US holding Bitcoin would amount to buying a hugely speculative asset with debt. A much better option would be for them to sell any BTC they acquire and reduce their debt (not that'll make much difference).
If they got their house in order - maybe then it'd be worth doing.
I'm not gonna hold my breath for the US to hold BTC on their balance sheet - but don't require it for my Bitcoin thesis anyway.
