Until I poll the API every day until the bucket changes and now I know your exact birthdate. This law is not well-baked.

That's only going to apply to children, since there's only one age group for adults. There are definitely ways to solve that, too. It's not perfect, but I much prefer it to laws that force websites to ask for ID, or laws that do the same thing by making websites liable for children accessing them.
