One of the arguments Hank makes in the video is that SpaceX is (via starlink) rapidly occupying large portions of useful LEO shells, which crowds out future competitors or users of that orbit (i.e. you can't put more satellites into the orbit without risking collisions, especially satellites that aren't part of the existing constellation), and that the natural consequence of not regulating orbital space in some way would be to lock in the first movers in an orbital shell as the only organizations that have access to that orbit.
I 100% agree but Starlink is the only profitable space division of SpaceX.
The truth is diverting money to space exploration is not that popular.
We only got the moon because we were in a battle with the Soviet Union about capitalism vs. communism. It was never about space or science. The instant the Soviet Union collapsed, we reduced NASA’s projects and budgets.
So while I’m not a fan of the circumstances, I need some way for money to go to space exploration and I’m riding this like people rode the Cold War as an excuse to build a moon rocket.

The instant we beat the Soviet Union to the moon we reduced NASA's projects and budgets. That's why the Space Shuttle was such a ridiculous kludge.

Which is utter bullshit. Quite painful to hear too. LEO is not your average american homeless stolen mart cart. Can we please rise to some more insighful level of discourse?
Nobody is arguing that space isn't big. The argument is space is big but dynamic, and launching enough stuff up there means that over a sufficiently long time horizon, you will have a collision between uncontrolled objects. This is not a theoretical concern, it has already happened [1].
Collision risk is significantly reduced by having maneuverable spacecraft with good conjunction prediction systems in place. But fundamentally, nothing is perfect and accidents can and do happen - you set a maneuver threshold based on an expected collision probability, but it's an engineering tradeoff: "spend the fuel to maneuver out of the way of everything, no matter how remote, or accept a small collision risk?"
And of course, when you are launching thousands of satellites, you will have a few failures that will become unmaneuverable hazards. Just the way it goes, you can't realistically engineer your way to perfect reliability.
So sorry, I have to reject your claims that it's "utter bullshit." Space debris risk is a well studied field, so much so that satellite insurance companies are starting to fold those calculations into insurance premiums. So yeah, it's real, and it deserves more than a pithy dismissal.

Whatever happens to Starlink, the debris in their new lower orbit would decay within months at the worst. It’s not one of those “thousand years imprisoned on the planet by a cloud of deadly debris” that we’ve heard about.
Not saying it couldn’t be bad if there were such a collision as obvi a really bad collision could in the short term damage Starlink and anyone else who decides to use that orbit, but this isn’t existential risk territory anymore.

Lead by example, my guy, I don’t know what side of the argument you’re even on
Can’t speak for the person you’re replying to, but many of us are more interested in best outcomes than we are in team sports.
insightful like your crude, substanceless objection?
