The money policies are so stupid, I don't know why they're so resistant to putting money in the hands of minors during this specific activity. She literally talks about wanting a part-time job! There are mechanisms for minors to be paid in this universe without the sky falling! If they don't want to encourage kids to do dangerous dungeon crawling, just ban the kids from the dungeons maybe?
Also, kids aren't going to pick up and carry their heavy dungeon materials for less than turning in a tin can. How often do you see kids picking up litter to turn in the empties? Exactly. So the problem wasn't even solved.
Potential fixes: Kids are allowed only on certain training levels and can't cash out (so it doesn't encourage them to sneak into more dangerous levels). They turn in their materials for government bonds of the CORRECT market value that they can only cash out when they reach the age of majority. If you get a guardian to sign some forms they can pay for a living allowance or something. The comedy can come from her taking out swarms of weaker enemies to get that living allowance and turning the kid-friendly training zones into something that looks like The Eclipse from Berserk.
I don't even get why the streaming is a thing, especially for minors. If you need to monitor everyone to make them follow the rules, just do normal CCTV. Or even the drones but don't make it public.
