I'm not really convinced by "John Carmack doesn't think it's a bad deal, so it's probably ok". He might very well be an incredibly talented game developer, but he also hasn't been in the position of being unknown in the space since the 90s. He also isn't an economist. However, I do think he makes a good point about accessibility. I also think that similar arguments are commonly used to defend MLM companies, which many rightfully still dislike.
I suspect he's more so talking from his position/experience as (1) a father, and (2) someone who launched his own (incredibly successful) business at a very young age.
