Short version is that in the absence of advanced comms, you have no option but to extend trust. I'm thinking here where inteervals might have been months, eveen years. (Historically, sea passage was not possible from November through May.)

Instead you had trust-establishing institutions, a role usually filled by religion, in virtually every pre-industrial civilisation.

Comms, from the scroll and telegraph forward, obviate this. Wearables, CCTV, desktop tracking, cellphone monitoring, all substitute surveillance for trust.
