I am a big fan of SpaceX, they are amazing engineers and scientists!
But when I watch such videos I can't suppress thinking that is not the way access to space should be. I still (I am 69) think that the way forward is with planes that could take off and landing on runways.
A fantasy for all the same reasons as putting up a million data centre satellites (it's roughly the same size project), but somewhat more useful as it turns space from one of the most expensive and difficult places to go, to a long-distance high-speed rail line.
Looking at the return trajectory for the space shuttle helps you understand the difficulties in combining aero-flight with rocketry using the same control surfaces.

Spaceplanes have a nice visual aesthetic, but absent something much more energy-dense than chemical fuel, they'd still need to be multi-stage, e.g. https://en.wikipedia.org/wiki/Northrop_Grumman_Pegasus#/medi...
My current fantasy for space access is an orbital ring: https://en.wikipedia.org/wiki/Orbital_ring
