I am convinced that this weird Phone Tapping thing may be the next evolutionary step from both social networks and the dead Internet theory (evolution not meant jokingly i.e. both naturally selected and the baby only got the recessive regressions).
The real solution hinges on maybe a future Turing award or Fields medal on physical cryptography for auth/integrity/privacy... but even without that. This is how Facebook got its "grassroots" userbase, from elite students verified via .edu email.
If a Friendster 2.0 actually doubles down on this physicality, and actually concentrate its efforts on making the very act of having to RE-TAP the physicality of a social connection, for example your friends may have an option to fund your trips to meet together if about to get disconnected.
Or of course it might end up being Facebook 2.0 and sell your Physical data to Cambridge Analytica 2.0 to make Grok beta emperor of Great North America CoProsperity Sphere
