No, you’re not wondering, not at all. You’re just trying to take a cheap shot. Nobody recommended a Koetsu. I said buying used opens up a lot of options and mentioned one example I have seen.
You can convince yourself of your cleverness but the plain fact of the matter is the more you twist the truth around to fit your predetermined narrative the more you undermine your own credibility. Do it enough you risk sounding like just another MDS crank.
No matter what you seen for sale somewhere, you have no idea what it was. Koetsu BLACK is the worst Koetsu cartridge, but the brand itself is one of the most expensive brand ever. If you seen a worst Koetsu model somewhere for ridiculous price then it’s a worn cartridge that must be repaired, I know very well the going rate for used cartridges.
The most expensive brand and the worn used cartridge is the worst combination ever for a buyer!
A buyer with low budget can find a perfect cartridge (MC, MM or MI) from the brands like Audio-Technica, Garrott ... etc.
Koetsu is a luxury cartridge that cost $5k and they are for experienced users who tried many different cartridges or for those who does not count money. Koetsu service is terribly expensive.
