It doesn't have to be an either or dichotomy. For example, you could pass laws that make it illegal for an online game to demand age verification, identification, biometrics, etc. The main reason for any of this are some corporate attorneys justifying their own salaries based on "what if" and scaremongering. Regardless of how much personal information they succeed at demanding at this stage, or how [in]effective it is at addressing their claimed problems, they will be back again pushing for even more until they're actually told a hard "no".
