His parents needed to kick him out or at least buy him a punching bag, would save hundreds of dollars in damages by now.
His mom is sunk cost fallacy in him to an extreme previously unthought possible, there is no way short of him assaulting his parents or him being arrested he will ever leave that house.
That being said he does /seem/ to care about his parents and they clearly love him so the prior is probably unlikely to happen, if he wants to punch something he has a wall.
His parents are also clearly rich so the fact their son is a drug-addicted loser who essentially throws money into a furnace 1-5 minutes after getting it 5 times a day on average is probably more of a "god damn it we should've beaten that boy straight when we had the chance" situation rather than a financial crisis for them.
He's fully aware that gambling is destroying his life.
After watching him for a bit now I think his drug problem is way worse than his gambling one. Sure, that may sound ridiculous, but keep in mind he actively broadcasts himself gambling, he hides his coke habit as best he can usually.
However you can tell pretty obviously he's doing it like, multiple times a night when he has it. Genuinely,
he may not even like gambling nearly as much if his brain isn't getting a constant hit of coke dopamine.
The few times he has streamed without snorting a line every 15-30 minutes he has been much better about withdrawing at least a little money and more self-aware that he is throwing actual currency away. Sure, this is probably to buy more drugs, but at the same time that's a level of self-realization unheard of most nights.
However, usually you get a stream like last night where he's snorting multiple times and goes insanely manic nonstop, from wanting to die to screaming like a lunatic from excitement on and off multiple times an hour for sometimes several hours straight, as long as he's getting juiced.
Not to mention drugs are pretty much eating 100% of any money he manages to pull from gambling because, well, it's a hard substance addiction.
Tl;Dr his parents are weak for not keeping him in rehab
