I would be interested to see a precedent from the past 120 years where the govt seized the treasury assets of a publicly traded company based on the 5th amendment. That's nationalization, not emminent domain seizure. And again, it would go directly to court.
Eminent domain wouldn't require a shareholder vote. The US Government has the ability to take property for just compensation for the public good, so I suspect they could buy the bitcoin at a premium if the SBR, as its characterized, is for the public good and for the amelioration of unsustainable debt, so if they paid $250,000 per coin at today's prices, the cash would inur to the benefit of the shareholders far above the present NAV, but it would be an interesting case. I believe in the late 1800s, this was under consideration for acquiring shares of rail companies. Here's an old ass article about this: https://openyls.law.yale.edu/bitstream/handle/20.500.13051/12997/38_5YaleLJ205_October1892_June1896_.pdf?sequence=2&isAllowed=y

I think we're entering unprecedented times.
