The cell capacity constraint is the main bottleneck that breaks the dense market math. A LEO satellite beam has a hard physical limit on how much RF spectrum it can deliver per square mile. In a dense suburb or city, you can have thousands of houses in a single cell. If 25% of them try to use Starlink at peak hours, the bandwidth per user drops to dial-up speeds. Fiber does not have this spectral efficiency bottleneck because you can keep splitting optical nodes. So Starlink cannot easily undercut fiber in dense areas; they are structurally capped by physics to low-density zones. Also, the $100/kg launch cost is an aspirational internal target for Starship that does not account for the capital depreciation of the launch towers, pads, and recovery fleet. If you model Falcon 9 or even early Starship launch costs, the Capex treadmill is much steeper. For a bondholder with a 5 or 7 year horizon, that front-loaded Capex creates a massive refinancing risk if the debt markets tighten before the free cash flow inflects. If you are rolling debt continuously to fund that launch schedule, the interest drag eats up the unit economics quickly. How are you accounting for the spectral density limits in your subscriber assumptions?
