Musk seems desperate to snatch defeat from the jaws of success.
And the market price of launching the 6528 satellites that they launched is around 11.3 billion dollars (67 million dollars per Falcon 9 launch, 169 launches). Assuming this is more or less the density of satellites they will maintain, that amounts to 3.7 billion per year just in constellation maintenance costs (to which we should add peering costs, personnel, ground station costs, etc). It's really not an easy business to maintain, unless it really does grow massively, and in a distributed manner (since lots of people in a small area will compete for bandwidth).
