Well, yes, few things are entirely immutable. Cities do grow and (rarely) shrink or disappear. But this is rare enough that it's useful to hang other data off of their names.
For example, take the locations used in time zone databases, where an official way to name a location is something like America/Los_Angeles. The assumption is that major cities don't get split across time zones and users know which cities they are nearby that they share a time zone with. Country names aren't used.
A lat/long pair would be more precise, but sometimes precision isn't needed.
