Look a little further into it. The blockchain can create contracts between two parties with certain rules and certain results. That way, if the contract is not executed, the person who didn't do the work doesn't get paid. Another example is medical records. Would you rather some hospital owns them where you have no idea if they are secure or of they are being sold to another agency, or would you rather have them at your disposal and protected with encryption? There are many examples of how the blockchain could replace politicians, lawyers, accountants, etc. It can cut out the middleman and all people have to do is sign into their account.

Of course this technology is new and there will be problems that need solutions, but so far, the possibilities are endless.
