Moving money always seems to involve a bank. How could the whole process be made peer-to-peer? I imagine some sort of nebulous cloud of users sending money to each other using darknets, reputation systems, secure messaging, ripple, bitshares, and bitcoin.
Would it be feasible to design a social-networking/secure messaging/reputation system/ledger DAC that could facilitate a nebulized exchange of value?
The hardest part of trying to do this would be trying to protect the exit nodes. How would you do it? Cash in the mail? checks from burner LLCs? burner banks?
The only form of money that is not lorded over by banks is cash.
