[Cogito]

Putting aside starship, from the very limited information I've seen it's not clear that the operating costs of this system will be comparable to Falcon 9 for the booster phase of flight.

It seems like this launch system will be more expensive per kg, and have far greater loads on the payload than Falcon 9.

I hope it works out, and they find ways to make it commercially viable, but Falcon 9 really has set the bar for success quite high.
