Psychobabble is a form of communication, but a poor one. It usually says more about the one spouting it.
The notion that anyone who considers chess a sport must be hoping to gain something tangible from the recognition is only slightly less absurd than the suggestion that anyone opposed to the assertion lacks imagination.
But you have to admit sports are a lot more popular and profitable than board games. So those are two prime suspects. It's not likely some people feel chess is a sport just for the fun of it. People are motivated by things that they feel benefit them. It seems MUCH more likely that the "chess is a sport" people hope to gain something tangible rather than doing it for non tangible reasons.
It seems much more likely that your limited understanding of human motivation is flawed.
People who seek financial gain from arguments on social media are fools.
