You may not see it as work... but the guy is literally getting paid for it.
No offense but it doesn't matter what you see or what you think you see - what matters is what's really happening.
And what's really happening is this guy has gotten REALLY lucky: He's got a job where he can have "fun/play" doing something that pays his bills. That doesn't make his "sacrifice" anything less because it's enjoyable (sacrificing time with wife/kid(s)). It makes his sacrifice enjoyable but he still has to make the same sacrifice that parents around the world make on the daily.
I guess I'd ask you honestly... do you see professional streamers or gaming streamers as working? Destiny, Vaush, Asmond Gold, pewdiepie, etc? I know streamers that spend 12 hours a day online engaging in content to make money - and a few of them have kid(s). They are having fun and making money while working their asses off to better their lives and, presumably, their families lives.
They aren't slaving in a coal mine or sitting with dead looks in their eyes in a cubicle but they are making money and ends meet. Just because they are lucky (and work their asses off) doesn't mean they aren't also sacrificing.
But I digress. I'm lucky enough to love what I do as well so I think the fact this guy can provide for his family by playing with toy is fucking awesome.
