We can get most of the way around problems like that, can't we? If there's no payment, you get an immediately collectable judgment against debtor, or trigger a transfer in other payment streams (from an employer, etc.) or transfers in non-cash collateral (which, depending on the success of block chain, could eventually include block-chain titles to cars, property, other securities, etc.). Usually, banks only lend to the cash poor but asset rich, so that's not so different. I see blockchain eventually becoming key for short term rental -- hotels, cars maybe. But the legal complexity between the law of hotel rooms and rental houses is huge.
