I always have my driver's license on me - even when hiking in the backcountry - as well as a homemade identity card (contact info for family, allergies. medications, etc.) A Social Security Card? I think I remember a white-with-blue-ink paper card I was issued (at my bank) when I was in my early teens. Haven't seen that card since (and that's been, ahem, many many decades ago). I've never needed a SS card in my life. Only the ability to remember the number that was printed on it all those years ago. I've bought houses, cars, gotten myself employed, etc. When do people actually need a physical SS card?
