You assume, without basis, that there will be no demand for such volume
at the price it will be able to be offered.

In the absence of a requirement for unused volume the economics assure it will not be built in a world (or off-world) where it cost order $50 for every lbm hauled into orbit.
If unused volume is built, those that have access to it will pay a premium price for it.
