All same-same for high-flight-rate RLVs.

Those are much more scalable (if properly designed) than heavy
lifters, by definition.

If your RLV has so low a payload fraction that it only pays off with
more flights than anyone wants...

And/or if your RLV cost so much to develop that ROI can only be
achieved with more flights than anyone wants...

You're just as dead, economically, as if you had Sea Dragons sitting
around with more heavy-lift capacity than anyone wants.
