and of course, the demand from the crypto mining market has fallen off a cliff due to low profitability.

This is wrong and misleading, I don't think you are in touch with the Market in Germany.
I can't speak about non-EU markets but I believe Miners in other parts of the world will be doing pretty much the same thing that EU Miners are doing, and EU Miners are currently buying GPUs as you 'll see in the E-BAY.DE listings below, only a few days old wherein used NON-LHR 3060 ti's with a couple of years 24/7 Mining on their back sold for around $1K USD.
I see the same thing here in Greece wherein new and used GPU prices spiked after a massive drop on or about 31 March 2022.
Miners are still in the market and they are buying in bulk b/c ETH's move to PoS has been indefinitely postponed for the 6th or 7th time in the last 8 years or so.
That means you are not likely to see GPU prices normalize anytime soon and you are not likely to see ETH move to PoS anytime soon (if ever) neither b/c Miners keep buying and they are no fools.
P.S.: Note how the Miners claim that some of these cards are "Neu" or "Brandneu" but if you believe that, I've got a statue in NYC to sell you.
