Cool to see this posted. I'm a Principal working at BCG in New York. I've been with BCG Gamma for a year and I've loved it. Smart, hardworking, and humble people doing some really interesting work.
So I'm the author of the OP. To be clear, I'm not advocating for Google or anyone else to force people to have only a single account. If people want to use multiple accounts and have multiple identities for anonymity or to separate "work" and "personal" Internet personas, then they should be free to do so. However I believe the option should exist for someone to unify their accounts through a single identity if they so choose.
