So none of this is about banning Bitcoin. It seems worse to me. Instead, I feel like the government wants to seize the means of Bitcoin production (mining) and start a digital war with other countries to have the biggest hash rate. This would mean individuals could no longer compete with mining.
Philosophically speaking you can define anything as anything (eg. Bitcoin and Speech) but that doesn't mean it is right!
But about this part I have to say it is impossible because the hashrate is already too huge and too spread around the globe for US to jump on board at this point and start owning a large enough percentage of it to have any kind of control. Keep in mind that US neither has the cheapest electricity nor access to ASIC production (the factory is in China).
