But ... Elon Musk has never once "come to dominate the market". He's always worked to figure out how to get government to give him ever larger amounts of money. He's built it up to the point where he gets close to 9 million USD per day from the US government (that's a stat only from his public companies. It doesn't include starlink military spending and the military part of SpaceX). Elon Musk's companies are something like Northrop Grumman/Lockheed Martin v2.0, not market-based enterprises, which they never were.

Tesla: cheating to make electric cars affordable, not by better engineering (in fact arguably way worse engineering), but by having the government pay (initially) 8000 out of a 45000 car, or close to 20%. Then continue by attempting, and failing spectacularly in an almost comical manner, to monopolize the battery market.

SpaceX: take a fundamentally bad business idea (there's plenty of private space launch attempts, but even the best go bankrupt), by ... getting the government to pay for space launches, in what is a very very bad deal (the government MUST have space launch capabilities. So it can never stop developing Boeing SLS. Therefore what is paid to SpaceX is paid ON TOP of what we pay to SLS, and is NOT a better alternative (as Musk screams), and so not any kind of saving. We don't have the numbers, because SpaceX is private, but all other companies trying it are 10x or 100x removed from profitability. Why would SpaceX, even if it has a 10x cost advantage, survive? And it is very hard to believe it's cost advantage is more than 2x or 3x if it exists at all)

Starlink: this has been tried, and tried and tried again. It just isn't profitable. SpaceX LEO satellites need to be replaced, 7000 satellites, every 5 years. That's 1400 satellites per year, or about 40 launches per year (you can only launch satellites together that go into the same orbit with very few exceptions), at a (subsidized by the government) cost of 70 million per launch. OPERATING (not building) SpaceX costs 2.1 billion dollars per year, not counting personnel, actual data transmission and uplinks, development of satellites and terminals. That's a minimum. The total market for internet in rural areas worldwide is ... about 300 million. The only real market for Starlink is military, and that means Europe, Russia, China, ... can never use Starlink. And even the US can't rely on it for several reasons (it's got a huge target painted over it's satellites and you can bet your firstborn Russia and China and Japan and ... have hundreds of experts working on destroying Starlink quickly. Hell, I bet the US has people working on that, even under Trump, just in case)

Explains a lot of why mr. Musk is so desperate to get a large amount of control over the government doesn't it?

Btw: does it really need to be stated that

1) every billionnaire is a financial engineer, finding holes in government tax policy, and if they don't admit this, they're lying.

2) mr. Musk's entire empire is utterly dependent on government spending. Totally. 100% (because all these companies would go bankrupt without government money, they wouldn't lose 10% of their income. They'd be gone). Therefore the idea that Musk wants to cut government spending is a bit ...
