You're not entirely wrong on it being a maximally cynical take, but I think it depends on where the idea originated. Yes, they expended a lot on engineering to make it real, but you can do that with any idea. I think what matters was if it was a feasible idea put forth from a reasonable source or if it was another grand delusion from Musk that everyone just had to make as real as possible despite their own misgivings on the idea.
