I have a genuine question, are we handing SpaceX a monopoly by allowing them to launch these satellites, or will competing companies be able to launch similar services? Will space be too cluttered for competition? (I'm guessing space is really big and that we can have _a lot_ of small satellites up there.)

Competing companies are able to launch their own satellites. Amazon is launching Project Kuiper satellites as soon as Q4 2022.

Monopolies are legal, anti-competitive practices performed to sustain monopolies are not (give or take that they are unenforced.)

Yup, spacex stuff is all LEO. Without input it all crashes into the atmosphere in a few years (3 I believe)

And we inhale it all. (Yes, I know it's insignificant; all things start insignificantly.)

this argument is pretty general; you're a priori attempting to prove that "acknowledged insignificant things are actually significant". This feels too strong!

Who's gonna clean after SpaceX' now? It's amazing that I'll get a $1,000 fine if I drop a small piece of garbage here in Irvine, but SpaceX can go away polluting the sky indefinitely without any responsibilities!

SpaceX is using their satellites to accomplish useful things for a lot of stakeholders. They also get special permission to allow their satellites to descend to the earth at EOL. These satellites stop orbiting quite quickly after they're no longer functional - they don't orbit indefinitely.

Your litter in comparison would be a totally different kind of problem, and evidently, it is a problem at human scale. That's why there are fines.

Is it possible to predict a geomagnetic storm, before launching?

It is, was, they were warned and launched anyway. I assume they calculated they could get through it and didn't. Live and learn. My guess is this was in budget an 'acceptable losses' to the constellation.

There's already multiple competitors in late stages doing this style of satellite internet. SpaceX just got there first.

SpaceX granted themselves the monopoly on these large scale constellations by being the first (and so far only) organization to develop (mostly from scratch!) reusable orbital rocket stages. Anyone else (without Falcon 9) launching the same number of launches/satellites would spend several large multiples of the amount SpaceX did, which makes it economically infeasible.

There will be other reusable orbital launch systems (although it looks like #2 will also probably be SpaceX, heh) but until that time everyone else is priced out of doing what SpaceX is doing.

It's got some analogs with TSMC and the latest process size microprocessors. Nobody else is prevented from doing it as well... it's just that they figured it out first and nobody else has developed equivalent technology yet.

If you read the article, SpaceX specifically designed the process to avoid orbiting junk.

Would spacex be liable if one of their satellites hits your car or house?

40 sats makes up about 2% of the current fleet - so a rounding error in cost and time. The important part of this news is how those 40 sats deorbit and leave no junk either in orbit or on earth.

An entire launch worth of satellites is not a "rounding error." The carbon impact of just one launch is pretty obscene.

These launches are getting SpaceX the money to advance to methane-powered rockets: they will literally make rocket fuel out of air and sunlight, making them absolutely carbon neutral.

A Falcon 9 caries just a bit more fuel than a fully loaded 777. Which is big, to be sure, but still a drop in the bucket just in terms of transportation.

This isn't quite a fair comparison, though, because it doesn't consider the energy requirements to refine lox.
