The private entrepreneurship must be rentable, government projects don't. That's why it's harder for private companies to develop large projects without lots of government money.
Recently there was a post on hn by someone who allegedly worked for Tesla before Elon musk was mega famous and this person makes two points:
1- a huge amount of Tesla culture was knowing how to manage Elon musk's stupid ideas and impulses.
2- Twitter doesn't have this culture so we're about to see what happens when Elon musk is surrounded by people who just take him at face value.
My thought at the time was: hold on, isn't that precisely how the entire planet (minus Tesla, apparently) sees him? Everyone seems to take him at face value and by know we've seen the pattern of how that pans out.
I remember a similar story as an image in a tweet/toot, but from SpaceX, and I've been wondering if it's true. It would certainly explain a couple of things.

Confederation Bridge, linking mainland Canada with Prince Edward Island (highway only, no rail) is 12.9 km long.

That's pretty insane.
