I'm playing Devil's advocate here. Yes, just a single year of production of 7542 is huge, but there are many batches. Say if you only want the first batch, I'm not say this is the best batch in any year, but many people would be only interested in the first batch, is relatively small. A few years ago, I was try to find the first batch of 2008 7542, but I could only find the 2nd batch. And I don't know is there any quality different between different batches, they might be just the same with only different wrappers.
If you really determine, you could still find any cake of a specific batch few years later but only with a much inflated price. But who know, the current Dayi bubble might burst.
