Unibodies do have a frame it’s just not a completely separate assembly like a ladder frame.

As others have said there are lots of places to jack a car. Nobody uses the flange on the rocker panels unless they’re trying to change a tire roadside with the emergency jack.

And before SpaceX the cost to do anything in space was extremely prohibitive.

As opposed to now…

With SpaceX they created re-usable rocket components

Nobody had done that before? Wasn’t the promise that they would do few quick checks, refuel, and send it back up same day?

Before SpaceX the U.S. was reliant on Russia’s soyuz to get us to and from the space station.

Nasa had do use Soyuz because crew dragon was late. SpaceX won the contract then underdelivered a late product. Basically exactly what ULA or Boeing would have done.

Wanna talk about Artemis?
