Warding off thoughts about other possible futures seems like a classic bias: in order to protect your self-image, you handicap yourself when evaluating other offers. This may be "natural", but it seems bad, like a fully actualized person would not need to do that.

And then the author of the blogpost takes advantage of this psychological tendency in order to keep people working for him even when they would have better options. The whole metaphor gives off manipulative, cult-like vibes to me.
