Sure.
I wasn't suggesting it would be done in a suave or impressive way. I just think it is unlikely that a set of events would occur that would lead to Chris giving up something particularly important to him.
The PS4 is an expensive toy, but selling it wouldn't net a ton of money. I would assume that Chris would cycle through a lot of options before selling it.
It would take a particularly odd set of events where the few hundred dollars he could raise from the PS4 were life and death, and there were no other options (e.g. downgrading a car) he could use to raise that sort of money. And by insider reports, Chris' financial troubles, while not non-existent, are not particularly dire.
The other scenario that would satisfy your conditions would be Barb insisting on him selling it, somewhat unnecessarily. I don't see this as particularly likely. As I understand it, Barb's badgering him is for money in general, without particulars. And she hasn't seemed to have a particularly strong opinion about Chris' vidya playing. If anything, she seems to vaguely support it.
