You don't? Google already requires ID for developers in Belgium [0], and it's complying with regional laws for age verification [1]. The EU is also starting to look at age verification [2]. I don't see how it's such a stretch that Google may want to expand this further even in the absence of government demands, considering the huge ad/data incentive for them to directly link accounts to IRL identities.
