Perhaps folks are unaware that there is a fairly decent market for SpaceX 'memorabilia'. A kit that is sanctioned by SpaceX is not the same as a homemade 3D printed kit, nor is it comparable to other RTF kits that don't have the same cachet. Ask anyone who bought a $30 SpaceX Falcon 9 kit how that turned out.
I get that a lot of folks have no interest in the model, maybe at any price, but certainly not at $150 + shipping. Anyone familiar with Estes will understand what they are buying, and it's not a museum quality model. But it is a decent, and most importantly, authorized model, of a revolutionary rocket that will look good on a desk, and the box on a shelf nearby. If that's not your thing, then great, more money for 'real rocket kits'. Do I feel dumb for buying one in the face of so many posts belittling the kit and price? Not in the least – in fact, depending on how it looks once I get it, I may buy a second one for my son, who in no small measure got his love of rockets by flying Estes kits as a young boy. I suspect for a lot of folks the meaning of the kit adds enough value to it to make up for the perceived shortfall in quality and details.
At least that's my take on it. I realize I seem to be in the minority here, but my guess is there are a fair number of folks like me who will vote in the affirmative with their dollars.
