Protecting children means protecting them from people who wish to harm them, that includes the government and platform owners, since these laws don't provide any actual protections to children from those two entities it's reasonable to assume that the law is trying to facilitate child exploitation rather than prevent it.
You have to keep in mind your idea of child protection is likely different from most of Americas'. The law makers' idea is to maximally enable them to perform (largely) uncompensated white collar work. Protected means that by the time they are 22 they have maximally warped their brain into an economically viable specialty and are in massive personal debt. If they make Roblox a $1M in the meantime of course that money won't go to their brainwashing, that would make them lazy.
