If someone had a heavy lift launcher ready to go, would they get anycustomers?

I guess it's really a dumb question, considering the history of
energia:

But the thought has croseed my mind: if a deep-pockets entity built a
lifter that could put up 200,000 lbs, or greater, might not someone
decide, 'hey, we could build a space station to lauch on that thing,'
or 'hey, we could use that to send up and assemble moonships or
Marsships [or such]?"

With the heavy lifter already developed and available at some
particular price per lauch, then someone ELSE could concentate on
applications: space stations for tourists, interplanetary craft, etc.
