You have a point here. It doesn't make sense that a company should get to keep the upside while having downside protection from the government. The problem is that the government makes the biggest bloated legacy nightmare of a corporation look like a 10 person startup. Between the two options I would rather have a pile of my tax money set on fire once every decade decade or so.
Anything critical for the nation should be run by the nation. I'd rather have a voice and the ability to vote out the people running that corporation. You don't get to elect CEOs.
