It doesn't just
launch rockets.
It operates the network too.
SpaceX is the only company that both flies the rockets and runs the satellite internet riding on them.

✦ The bottom line
SpaceX pioneered reusable rockets, which made launch cheap. Cheap launch is what made Starlink possible — and it's the only company that both launches the rockets and operates the satellite network on top.

A moat
A moat is a durable edge a rival can't easily copy — the thing that protects a business even when competitors try to catch up. For SpaceX, the moat is owning both halves at once: the rockets that get to orbit cheaply, and the satellite network that earns money up there. Most rivals have one or the other; SpaceX runs the whole loop.

Competitive advantage / barrier to entry
To truly compete, a rival wouldn't just need a great rocket *or* a great satellite network — it would need to build *both* a reusable rocket program and a giant constellation, at the same time.

Here's the loop that's hard to break into. Reusable rockets make launch cheap, so SpaceX can put more satellites in orbit. More satellites mean more subscribers, which means more cash. That cash funds the next rockets — Starship — and the next wave of satellites, which makes launch cheaper still. Each half feeds the other. A rival can't just match one piece; to compete on the same terms it would have to build both the rocket program and the constellation, and fund the whole loop while SpaceX is already spinning it.

Down from $86 a year earlier — on purpose, as Starlink expanded into lower-priced international markets and grew the subscriber base. Falling price, rising volume.
The moat is real — it owns both the launch *and* the network.
One honest caveat: that loop isn't free. Starship and constantly refreshing the constellation still need heavy, ongoing capital — the same cash-hunger Chapter 2 flagged.
