When you have a hammer, every problem looks like a nail. People are trying to blockchain everything. There are other solutions. While blockchaining may make corruption difficult, there are other ways to get corrupt people out those situations. Licenses, background checks, Laws, regulations, inspections. A lot of wisdom has gone into the social edicts of everything from mail, home inspections, electric and fire codes. These regualtions came out in a time that did not have blockchaining. While I love the fact that you can use blockchain technologies with people you don't trust; sometimes it is better to make sure you only deal with people you can trust. If you can't trust a man, what difference does it make if he writes something down?
