The M1 MacBook Air and the M1 13" are about the same prices as the Intel versions yet are far more powerful. The M1 Mini is $100 cheaper than before. Same for the 24" iMac. The discontinued high-end 13" Intel MBP used to have a weaker CPU and far weaker GPU than the 16" (and is now out-performed by the low-end M1 13") - 14" MBP is now closer to the 16" MBP in performance and specs, and $1999 was actually the price of the old i7 13".
If you ignore the Studio Display and pair your Mini up with a third-party display (or just plug it in to your 4k TV) you've got a pretty affordable and powerful "entry level Mac".
The M1 Studio is really a new, cheaper alternative to the Mac Pro ($6k+), iMac Pro ($5k+) and the higher end non-Pro iMac configs that cost $3200+ - again, combine a Studio with, say, a nice $600 third-party display and you've got a $2600-$4600 alternative to what was previously a $3000-$6000 range.
The issue really all comes down to the demise of the 27" iMac and the $1600 price of the Studio Display vs. the old ~$700 difference between a base 27" iMac and an Intel Mini with a comparable CPU. If you wanted that particular 5k, 27" display (which was a sweet spot for MacOS) and built in camera & sound, you're stuffed.
You are right that the new products may offer better value, but that is not exactly the point here.
You see, the M1 MacBook Air and Pro and the same price as they used to be, and they are far more powerful. This is true, but for the entry-level.
The 16-inch MacBook Pro costs $2499 now (the base model). Yes, it is far more powerful than its predecessor, which means it offers a much better value. But the predecessor started at $2399. If you look at some history, you will see that the 15-inch MacBook Pro with Retina Display launched in 2012 with a $2199 price tag. And that was already up from 2011's 15-inch MacBook Pro which started at $1799. Yes, it has been 10 years now, and there is inflation, but the whole logic of tech products is that they get cheaper every time.
The 14-inch MacBook Pro is new, but it replaces the 13-inch model. And starting at $1999 is a lot. The 13-inch MacBook Pro with Retina Display launched at $1699 in 2013 and people were already shocked.
The 24-inch iMac starts at $1299, which is OK. You may mention that the last 24-inch iMac prior to that sold for $1499. But that was the large model and not the small one. It was replaced by the 27-inch iMac. The current 24-inch iMac replaces the small iMac, so they should not be comparable.
The Mac Studio is a cheaper alternative to the Mac Pro, but, really, who needs a $2600-4600 desktop that is not even suitable for games? Again, as I mentioned earlier, creative professionals! The Mac Studio should be exciting for creative professionals. But that is only a very tiny percentage of the world's population.
My point is that all of this is fine, and Apple new Macs are terribly good. But they are expensive as well, and not suited for the general consumer. The value is great, but most people do not need all this power, so they do not need to spend this amount of money. The options available for the general consumer are much narrower now under Tim Cook than they were before. Yes, the 13-inch MacBook Air is excellent value, and so is the 24-inch iMac. But what if the general consumer wants a different size?
Creative professionals, which are 0.5% of the U.S. population, and even less of the world's population, get plenty of options. General consumers do not.
