Seems like most of these can be done without blockchain. Some are not even 'real world' at this point, but just experimenting. As others have pointed out, when in doubt - 'do you need a blockchain? no'. Overhyping them for use cases where they are not needed will have a negative effect on trying to get support for the places where they might actually be useful.
