It was way more than that, no data chains, no parsec, no secure message relay, not fully encrypted comms, no udp hole punching (it was upnp and direct), no bootstrap cache etc. etc . Much of that will be alpha3 and all the alpha3 work is putting these things in place to secure a routing network.
With vaults on top then farming does add to the security and is an empirical part, however without a secure routing underneath the safecoin security vanishes to zero.
