Mac Pros not being MacBooks is an interesting point. A wide range of products leads to a spectrum of quality. Die-hard fans may be the ones in the high-price/-reliability quadrant, but maybe 5x more are attracted by the lower-price/-reliability quadrant. I suspect that MacBook was in the starter quadrant, and the actual professionals are in the other.

Sometimes things even shift in a single product over time: establish a good reputation, then water down the product a couple years later. All the die-hards leave, and the rest are none the wiser.

IMO $6k is just too much for a Mac Pro, except if it rocked a 3990X (do it, Mr. Apple!). It might actually be worth the money, even still. Apple seems to support Mac Pro OS upgrades for ~10 years after release.
