I expect introverted individuals playing on their own in the wilds (or "hunting") are nature's answers for societal insurance. If some catastrophes strike at the tribes/HG bands' main encampments, some cultural memory and genetic diversity persist for the next band to reclaim that site.
After all, humanity natural niche is persistence hunting and gathering-scavenging.
And of course, hunting itself took a long time to do, especially if you are doing persistence hunting with primitive tools and maybe fire. A long time to be lonely and tolerating it.
