Most people are reluctant to hold the public key, and even if they try to do it, some experts will still mess it up. Storing your own private key is as terrifying as hell. It's important to remember that most people don't even have the responsibility to manage money, let alone carry a secret number with them so that anyone can steal your money in a second. In the future, KMS will be a huge market. Some KMS solutions may even become like crypto-banks.
