I've seen a similar usage of the expression "social creatures" ("social animals") before, and it bothers me. Firstly, because I've known several loners who would take issue with what's being suggested.
But secondly, because the expression originally implied nothing of the sort, and still doesn't in biological jargon (which I believe is where it is/was most commonly used).
It was Aristotle who first used the expression "ζῷον πολιτικόν", and he used it to mean that humans exist in large ordered agglomerations as a matter of fact [0]. He also included bees and ants among the "political animals", but I don't think he ever said anything about any of them wanting company for it's own sake. And, at least in the beginning of his Politics, neither does he suggest that humans want it for it's own sake, either. Biologists, on the other hand, still use that expression with a meaning similar to that of Aristotle (animals who happen to live together), while including other groups [1].
Now, this wouldn't be a problem if in common language these expressions merely meant something else than what they do in biology, or what they mean in Aristotelian exegesis. That would be fine. But instead it seems as if the usage in common language relies on the usage in learned contexts to do a little bit of semantic sleight-of-hand, and suggest something else than what was originally meant e.g. "Humans have an inherent need for company: Biologists say we're 'social animals'".
Otherwise, the statement would have no authority behind it in common language. Instead, it would be just an unfounded assertion. In fact, that there are people who disagree with it already suggests that it is, at least, ill-founded. These are the people saying "No, we don't". But instead, readers are nudged by the usage in learned contexts to take it for granted, without further justification.
Either way, it's a bit like when someone conflates term "observer", as it is used in physics, with the term as it is used in common language to suggest that people can walk through walls if they wish hard enough.
