Your inability to grasp the fact that the chasm between AAA and MLB is larger right now than ever before and there are essentially zero prospects who come up and succeed immediately anymore. It doesn't mean people are "prospect nut huggers" as you so eloquently say, it means the level of patience required for hitters to develop into quality MLB hitters is much greater than it was even 5 years ago. Guys like Horton, Skenes, and Chase Burns just aren't spending time in AAA for hitters to see that quality of pitching and make that jump to MLB easier. Nobody is saying Shaw is going to hit like PCA, they're saying he's likely to be a lot better than he's been so far once that adjustment fully happens.
