That’s true today, but it is a rule that was created with the intention to gatekeep. The image of chess as an elitist sport is not spontaneous, it was manufactured to exclude and marginalize people away from their perfect sport. Then they wonder why chess popularity is in decline and tournaments see reduced number of participants year after year. Until the advent of internet streaming and online gaming, chess was in a death march. These ancient institutions don’t understand the world anymore and blindly reproduce traditions from a discriminatory, classist, sexist and racist past uncritically.
