Again, none of what you're saying will make the US government, especially the current administration, care, as they have not cared about many things with consequences either; you're applying logic where there may not be any heed to it.

As well, it is a false equivalence to say that local models are only Chinese and otherwise we would use cloud models, but there are American or European ones, so a ban would simply force companies to use these, even if they are inferior to Chinese ones. It's simply a matter of national security to the US government, and they will not care what random people in media say.
