The case study results would be "make a product that's really hard to make and that people want"

Fair, but sort of my point. Make a extraordinary superior product in a very niche market and educated consumers will pay. Sure, there will always be uneducated or just "frugal" or cheap consumers but they are the fringe. Example are luxury brands such as Mercedes or Rolex. A hot take, but can't be denied as well Apple.
