We're cheering him because he's leapt out ahead of everyone. Everyone else was content to just shovel endless piles of cash at the Old Space companies for expendable rockets with no real plan to get people out there. Congress liked it as a jobs program, the contractors loved the money, NASA was getting what they could. He's actually moving forward with plans to establish a no crap continued human presence in space. NASA sorta on board as they are paying for both an in orbit refuelling demo with Starship and a lunar landing variant.
As for showing the reentry destruction, it's really 50/50 for that part. Super Heavy, the Booster, that's the easy part, other than having more and more powerful motors than have ever flown before. Landing it, that's an extension of something they've done more than 150 times.
But Starship, the second stage? That thing has so much new stuff. Reentry with stainless steel. New heat shield tiles that are clipped on. Not glued. Huge movable control surfaces. Completely different shape than has ever reentered before. If it makes it this first time it would be amazing, but most folks don't really expect it.
Good thing is that there are literally two more in the wings ready to go. Unlike old space, they are really planning on assembling these like Boeing does aircraft.
