While it is a wonderful thing to see gachas being banned i'm afraid it will not stop there, these people that call themselves creators will simply find new means of luring consumers in with another "mystery" concept that in reality allows them to conceal rushed and often poorly made products behind it. Like a casino it does it's best to appear innocent while vulnerable customers such as children and other poor souls that are easily addicted becomes its victim.
These people with a abusive nature often defend themselves with "they have a choice" i'm sure the casino say the exact same while having set up traps before you even enter Las Vegas. The trap with gachas is that they gate a "rare" which is in reality not rare at all, they use this word in order to get you to buy as much trash as possible on the journey before you get to the destination "rare".
Another excuse they like to use is "it's a game of chance" but once you start digging for the truth it becomes quite clear that it really isn't a game of chance at all.'
The more gachas they put into their machine regardless of the chance the event use (usually 3-7%) they will always get more money out of it regardless of who wins what, that's something you can count on.
At the end of the day many of us buy mystery boxes and gachas, often because the products we want only comes from that, but for your own sake stay away from Mystery products, they are obviously designed to deceive you just like a casino is.
