I think u/credit_guy means that with Starship the U.S. could put a constellation of anti-missile missiles in orbit and keep them there for the long haul. If Falcon 9 can put up 5,500 sats in a few years, Starship could greatly increase the rate at which the U.S. can build not just comms constellations but also reconnaissance ("spy") constellations, missile defense constellations, anti-sat constellations, maybe even nuke constellations, who knows.

I suspect that missile defense constellations would have to be truly gargantuan though, because of some N thousand missile defense sats most will not be able to reach the missiles being launched at any given point, thus to counter a 1,000 ICBM/SLBM threat the missile def constellation might have to have 20x -maybe even 100x- that many space-launched anti-missile missiles. That seems prohibitively expensive even if internal Starship launch costs ever come down below $5 million each.
