Given that they've sold...
...more than half a million packs of Polaroid film that they bought up in the original liquidation, over the last year and a half, it seems like there is a market- just not the one you seem to think.
My experience with this is that Polaroid is an excellent niche market, just not the mass-market product you seem to assume. When you're at a party and you offer someone a polaroid snap, you don't just take a picture, you also give them a gift. There's a unique tactile element, too, that you don't get from digital photos, where everyone clusters around to watch the photo develop. There's a magic in watching it- and people seem to respond to it.
If you've got an old Polaroid hanging around, and you attend gatherings, you could do worse than to blow a tenner on a pack of film for it and see.
Then there are a number of factors that really make Polaroid irreplaceable- firstly, that lack of a negative means that once the photo's developed and set, it's set in stone. This is something digital formats just can't replicate, and it's something that gives polaroid photos more weight in court cases. This is very handy when you want to sue that builder who screwed up your house.
Secondly, the film is huge compared to a 35mm negative- easily the largest consumer format- which means you can actually blow them up really large before they lose detail, at least if you're using an SX70 or Spectra camera that has a decent glass lens. These cameras are far more compact than other large-format film cameras, and a lot cheaper too (you can pick them up for a few quid on eBay.)
Thirdly, if you're at a party and you take a picture of someone, and they don't like it (or they're doing something that might get them in trouble...) then you give them the photo and they know for a fact that you don't have a copy to upload to the internets. That's a big win in my experience.
