This is a repeated trope and more ridiculous each time I hear it. Starlink is a private company that is in the business of selling the US Government as well as consumers its services. You can't just "nationalize" it on a whim; after all, the US isn't Cuba.
GPS was always owned and operated by the US military so it's an apples and oranges comparison at best.
You seem so alarmed by my proposition to nationalize a private company. Would you have been so alarmed if the government were punishing people for crimes without due process?
Governments can do exactly that. The legislature can change the law to enable it if necessary.
> the US isn't Cuba.
it is not just communist countries that nationalised things. Much of Europe did up to the 1970s, lots of Asian democracies did.
I suspect you're about to have your eyes opened to just how the american right feels about pre-neoliberal europe and asia.
There was a lovely radio interview of Neil Kinnock (former leader of the British Labour Party) many years ago in which he described the reactions of some Americans to him being a socialist (and not the British equivalent of the Democrats). One woman said "You can't be socialists, you're too nice".
