Given the price, I could see some Vison Pro's being passed around (re-sold) multiple times actually.
It could easily be one of those type of products that many many want to try and see what it's like, and enjoy the experience for a while, before deciding it's not really ready for prime time, and now they've had the experience, they have gotten over it and are happy to wait for a lighter/slimmer upgraded future model when the software had matured more.
So then sell it on, not losing too much money, onto the next person to go through the same process.
I could see this happening to some vision pro devices multiple times.
Heck I could even imagine a small market for lending out the device for a month or two for the right price.
Guarantee there are many on these forums who don't want to spend $3500/$4000 but would love to pay perhaps a couple of $1000 to play with one for a month.
