"Enthusiastic" doesn't mean "stupid". And right now PCIe 5.0 is stupid, because there are zero commercial products that use it (SSDs or GPUs). Then there's the fact that getting PCIe 5.0 support in your PC is expensive, in terms of motherboards (and even more so if you're going with AM5).
But even if PCIe 5.0 motherboards and devices were cheap and plentiful, in and of themselves they would bring few tangible benefits. The advantage of SSDs has always been their random access speeds, which is a property of the NAND flash, and was and still is available on the slowest SATA models. Moving to NVMe has allowed faster peak read and write speeds, but those are irrelevant to the vast majority of users the vast majority of the time.
So really, PCIe 5.0 in consumer devices is, right now, a solution in search of a problem. PCIe 4.0 has proven that it is pretty much good enough for 99% of consumer needs, and while I'm sure use-cases for the higher bandwidth of PCIe 5.0 will become apparent, right now they just aren't there - so neither is the reason to upgrade. It doesn't help either that we're in the middle of a recession.
