Are you a US citizen? And if yes why centralize the ban, why not make it known where the ban you think that it can happen, US isn't the whole world you know, but even at that I don't think with the adoption greater than it was in past, that the ban on bitcoin would materialize,
While US isn't the whole world, let's not forget they're a world power and what ever they do has a major impact on that section of the global economy. If the US government was to successfully ban bitcoin (which is quite impossible) the rest of the whole would follow suit especially those nation that has a strong relationship with the US government or rely on them for aid).
US has to be used as the references point because among all current government if there was a government we should be more concerned about is the Biden government. He's anti-bitcoin and sooner or later this will begin to reveal itself.
