It doesn't. The PGP web of trust means you actually trust (albeit indirectly in many cases) the other party.
Because this new system is blockchain driven, you're not actually being asked to trust that someone is who they claim to be, just being asked to accept that they got control over the 'name' they're using first and can prove it via the BC.
