Think about, lending in a traditional way contains many types of uncovered loans - credit card, personal and consumer loans. Where the important thing is to predict that the potential debtor will or won't pay back the loan.
In blockchain where every transaction is visible, it is much easier to predict who will pay and who won't. Also, a blockchain can register credit score, which is built upon previous credit history - if you build your credit score many years long, you won't it ruin directly.
Blockchain also makes it difficult to hide for bad debtors.
I know many things mentioned in this white paper
https://www.maxicreditcompany.com/whitepaper.pdf will be available only in the next years, but the whole blockchain, smart contract technology is about the future, not about the 0,1% who use it today.
If you are really interested in lending via smart contract send me a private message.
