Elon is not the one who failed to pass the twelve appropriations bills throughout the year that Congress was supposed to. He's not even a congressman. He can give his opinion about what to do after that failure, and Congress can listen or not.
If you think it's awesome for a small group of oligarchs that don't include the vast majority of Congress but do include lobbyists to release a bill over a thousand pages a matter of hours before a vote, with no time to read it, right before the Christmas break and under threat of government shutdown, intentionally and annually? That's certainly an opinion you can hold. But if you're gonna assign blame for it not passing, assign it to Congressmen who had the absolute audacity to insist they have a chance to know what's in it before passing it rather than anyone who doesn't have a vote.
