I'm not exactly a Musk fan, I will not follow the machinations of any billionaire anyway. I don't like the environmental toll that electric cars reap through their huge expensive and basically toxic waste batteries, I think starlink will eventually cause Kessler syndrome not to mention the 500kg of toxic electronics they add to the atmosphere every time one deorbits which will be thousands a year, I think the idea that you need a substation just to charge a tesla semi is hilariously obscene.
Aside from all that, the ptivate rocket program is not doing well. It may be impossible to hava a private space program that is for profit. They can't afford it. I saw the video and it looked like several of the rocket engines had failed even before the separation so I'd bet the excessive G-forces due to the instability mechanically locked the clamps. You'd need explosive mounts to overcome that or something with no guarantee the second stage could stabilize the rocket.
The failure of their engines is a common issue that they've not addressed in subsequent design schemes because rocket engine reliable designs are very very expensive.
Good luck to the chief twit and his randomly idiotic/ingenious endeavors.
