Original Blue Note LP Values - Vinyl Madness!

I've been using Discogs to help me label song files of my Blue Note collection. In doing so, I am astounded at the prices of some of the original LP's being sold. Who in their right mind would pay thousands of dollars for a single LP? Also, what makes these so rare? Did they make like 4 of them?

I found an article written along similar lines
Blue Note Record Collector: The Outrageous Auction Prices of Vintage Blue Note Vinyl Records

A couple of examples...

 

well, in the lower example, Sonny Clark, for example, the last sale was August, 21st, 2021 .. so either no demand or they are priced way too high and no one is buying them

 

Crazy. They’re asking 4x the median price. Nonsense.

We’re hitting a severe global recession!

 

Just hit eBay completed auctions.

 

Blue Note First Pressing Quantities

if i'm interpreting this correctly it looks like an initial pressing may have been ~2500 copies.
probably not many of them are still around today and even less that are in M/NM condition
