The Gish gallop continues...
The descent stage wasn't "obliterated" for the same reason a runway isn't shredded by a Harrier jet taking off - the force needed to take off was not sufficiently large to overcome the stuctural integrity of whatever was underneath.
Interesting point about Harrier (and other people use helicopters for the same example) but in the end it fails.
Firstly a harrier jet never takes off from a ricketty platform supported by 3 legs, widely spread and not under the point of lift off. They take off either from concrete on top of impacted earth or from specially constructed reinforced runways on a ship - that presumably are engineered to cope with such stresses.
Secondly, a harrier jet and helicopter depend on lift heavily on the movement of atmosphere to supply support and lift. So a helicopter certainly won't work on the moon. Nor would a harrier jet, although probably something not entirely dissimiliar to a harrier jet might work. A harrier jet is still very dependent on lift and/or support for its wings. And I assume that a harrier jet has a ceiling that once the atmosphere is too thin it can go no further.
In the end, I don't think you can get past Newton's 3rd law and you to sending an equal and opposite force down on whatever you lift off from and frankly I don't think something with this structure has the capacity not to collapse in the middle
Although admittedly this was taken on earth, how heavy were those suits again?
