Re: Good is good
"That's what the question should be - would my country be better off with such a law?"
I'll analyze that, probably too much, in the next paragraph. Before I do, I must first state that you have to ask one additional question: "would my country be better off with the ability to create and enforce such a law?". There are things we'd all like done, but some of those that haven't been done have been left without legislation because there is too much risk of abuse should the required powers be granted. That also needs to be asked.
Let's turn our attention to this specific law, though. I have a dim view of "influencers", and I don't particularly care when they don't have success at influencing. If they all decided tomorrow to quit and do something else, I would consider it a positive. Let's see what this law does to restrict them. The first thing is that it tries to stop them asking for money, one of the more annoying things they do. Yet why should this be a problem? I know, for example, various projects where the creators ask for donations, from podcasts to open source software. If I don't like them enough, I don't give them money. Why should it be illegal to ask for or receive money for something any user can avoid at will?
Next up is making the services liable for refunds when a child uses an adult's credit card to pay. This makes perfect sense, except it's in the wrong place. It's always an issue when a child uses money that isn't theirs to buy something, no matter what they bought. Parents can deal with this themselves by not giving their children access to payment methods or by having rules about their use. For instance, they could do what my parents did: I knew how to spend their money, but if I did it, I would have to explain what, why, and how, so I only did so when it was necessary. I don't have a problem creating a regulation that clarifies what happens when a child spends the parents' money without permission, but the important thing is the payment, not the payee. If a child takes the parents' credit card and pays a streamer, it's the same problem as if they chose to buy a ticket or donate to the Linux foundation; it still wasn't their money to spend. As such, putting this regulation in a law that's targeted only at streamers is doing this the wrong way.
One more aspect to discuss is the curfew on watching this stuff. They're right that children can stay up too late and have negative results, but that's not really a thing they should legislate to fix (and also not something they can). Children can stay up late doing any number of things. In my childhood, it would be reading books. If the government had tried to pass a law banning me from reading books at night, even if it would have made me more alert, it would have been a bad idea. The right approach is for parents to decide what restrictions to place on their children or to let the children make some of these decisions. In my case, I simply noticed how I felt when I had read too late and decided I'd have to change my schedule to not have that happen next time. I also noticed that, sometimes, my teachers would assign homework all at once and I'd have to stay up late to complete it all, but somehow I'm guessing China doesn't consider that cause of late nights to be a problem.
So to answer your question, I do not think my country would be better off with such a law. It has one useful element that's misused to target one group when it should be generic and it has two aspects that give the government power over something it has nothing to do with. I can say this without liking the targeted group. I can say this while agreeing that, if I had children, I would prefer them not to pay streamers, stay up late to watch them, or use my money for it. I can even say this knowing that, if I had children, I'd set rules to prevent them from doing some of that. That's a decision for parents to make, not government leaders.
