Anonymity may not be of great import but I believe one day people will realize just how much tracking comes with credit cards and the like. I can't even buy a birthday gift without it being available to my SO in our account details. How is that a surprise? Sometimes giving my nephew a bit of cash is cheaper than a gift card that might require an activation fee. Sure what's two dollars but still. There are plenty of reasons to use cash without need for anonymity, so I don't think it's going anywhere.
