And keep in mind the lifetime of these satellites is relatively
short (from memory something like 3-5 years), so this isn't a "one
time" thing. If Starlink is successful, SpaceX will be
continuously launching its own Starlink satellites for some time to
come.

Yep. They're going to have to replace something like 2500 satellites
a year once the full system is up.

A huge investement that has to constantly tread water? Insanity!
