Do we? Our SSN is not a unique number, and not just because the keyspace is too small for our population. (It's worse: some of the prefixes are geographically related.)

Even if what you say were true, handwaving this as unimportant because it only affects people over the age of ten seems a bit silly.
The post that I replied to is almost entirely incorrect as it relates to available SSN “keyspace” (misnomer), uniqueness, etc.—-for which geographic prefixes and group numbers are relevant.
I supplied direct sources, so no idea what your “even if what you say were true” skepticism is rooted in.
