Well, I wasn't thinking just on price but from a strategical viewpoint. If the point is making launches affordable and routine, you want predictable price and steady supply. The future of oil is grim, while organic waste for methane has a steady supply. It would be cleaner and net carbon credits. Apparently it's safer to store and handle too. Maybe that all adds up to significant savings, specially in the long term, when margins get thinner as more competitors enter the market? Haven't done any math though. Never thought propellant was such a small fraction of the price though. Learn something new everyday.
