This analogy falls apart in several ways. The majority of all funding for SpaceX comes from the government. This isn't like a paper company that has massive contracts outside of the government. Furthermore a paper company is a dime a dozen and probably not a national security issue like the sole provider of needed launches.

Governments would probably never need to take over a mundane company like a paper producer, but they most certainly would need to take over a critical supplier of national security needed services because it is run by a space Nazi.
