Have you seen a 3080 somewhere? Like in a store where you could buy it? :-). Could just be the Bay Area but those things seem to be pretty scarce.
I can definitely see why people want the RTX 3090, it's a pretty good GPU... but I don't think there is any way people could do the cost/benefit analysis and decide that $11k is the right price to pay.
No matter how you slice it, this one "fell off the truck" somewhere, it's an unreleased product, you're not supposed to have it yet.
This mainly applies to people who need to run GPU nearly all the time, not just a couple of hours per day.

And of course you can't play ultra high end game settings on the cloud.
