The point is YOU have the choice of who YOU choose to fulfill role X, and you can spread the tiny responsibility across multiple entities, while removing the liability that one of them could just impersonate you anytime. It’s totally up to you, and you can recreate the legal custodian relationship if you wish, but then they or their employees would technically have full power over your account.
Are you the kind of person who LOVES signing in with Facebook, and trusts them to safeguard your keys and identity in their nice centralized database — if anything goes wronng you’ll have the legal system, another nice top-down system of laws and enforcement, to correct everything, right?
I don't have Facebook, but from what I gather they are not in charge of safeguarding anyone's keys or identity. So... yeah, I have trust in the rule of law. For example, banks pay millions every day to customers in compensation for improper charges as a result of court rulings. If you can't trust the rule of law you have bigger problems than worrying about Facebook stealing your identity... but I'll leave it here.

Most individuals cannot bear the weight of corporate lawfare. Congrats on winning a nice case and getting a good pay out. but that is survivorship bias.
