He would get a hell of a lot more flak for accusing him of cheating. Instead, he just makes it obvious what he thinks by refusing to play with him. I think it's classier.

A human brain isn't fully developed at 19, just because we send 19y olds off to kill in wars doesn't mean they are adults and it certainly doesn't indicate infantilizing a young adult by allowing them growth. If we're talking about a 39y old man, then you can start proselytizing and comparing.
Most of mid-life -> older is validating the "youth is wasted on the young" quote and turning into an old fart. A fudge-ton of humans never had this chance, that doesn't mean we can't grow and allow for it now where circumstances allow.
I find this similar to the student loan forgiveness/free State College conversation in the US. It is almost as ridiculous as "originalism" in interpreting the U.S. Constitution.
