Saying it just isn't plausible that ambitious thing will happen without an argument for why it won't happen... doesn't really lead to an interesting conversation. Especially when all the arguments for why it is possible already exist in public forums.

I mildly disagree with you, but I can't even begin to take the other side of the argument without knowing why you think the price estimates given aren't plausible (or even basic facts like what the cost you are using for the Falcon Heavy is...). Other responses to you spew out random facts trying to argue that Falcon Heavy is expensive in ways that Starship isn't, but I really can't tell if those random facts are even closely related to why you think it's implausible.

The reason I thought it was implausible is because in my experience, such dramatic drops in price never happen in only a few years.

The other responses did help clarify how it can occur with Starship.
