An alternative would be to send up smaller spaces that connect together
like bubbles. I guess it really depends on what is considered small for
launching. If to objective would be to have a living/working space of say
a 10x10x10 feet, you could send it in a package as small as 4x4x4 and it

Mauna Kea and Mauna Loa in Hawaii are both nearly 14,000 feet. Both
have mostly paved roads to their summits, and both roads
align. Even if so, punctures in a chambered inflatable are
easy to plug with anything sheet-like.

One of the problems I encountered was how do you build circuitry to
survive the launch. The forces involved will destroy most electronics as
they are now built. Solids state is not very solid after 15x
gravitational forces.
As they are now built - for what?
They've built nuclear
