Such superorganism traits arise only if they are evolutionarily advantageous, and only when evolutionarily pressure selects for those traits. However, overpopulation previously was never really an issue, high population density was the exception rather them the rule, and various nation states clamored for scarce resources through war. This means that such forces haven't been part of our species for long.

In such an environment, wouldn't evolutionary forces be less likely than, say, ubiquitous xenoesteogen exposure from new chemicals like plastics or a vastly different diet and lifestyle from our evolutionary origins?
