Although starship is not "proven", you can say that the architecture is one that atleast theoretically works. And they have the data, and it is an order of magnitude cheaper as my previous comments have said.

This next year they have the hardware and permission for 25 launches. So within the end of this year your comment will no longer be valid.

I heard the next year there will be 100 launches and they all will be self driving too.

And you will be able to buy one and rent it out for 100x return on investment.
