I don’t think that’s an “if” at all. I firmly believe that that’s exactly it.

The same behaviours that we needed to evolve are harmful now that we’ve reached a potential “post-scarcity” stage.

To put it more bluntly, the drive to compete for resources in order to survive is what made us the dominant species. Now that post-scarcity is essentially upon us, our nature is to create artificial scarcity in order to satiate that drive for competition. And it will be the ultimate end of us.
