That's actually done already in XMPP (Jabber). Federativity, voice calls, E2EE, direct and offline file exchange, no sms verification and other bs, max privacy and convenience.

Sure, XMPP could go a lot further with a central body which set a minimum set of XEPs to standardise and maintained a blacklist of bad hosts though.

Signal could have helped a lot here (so could others, to be honest).
