This is just a list of current ideas (mostly) and implementations using blockchain. Calling it a list of "real world use case" is far fetched. We have yet to see whether it actually works.
It seems to me that a reasonable test whether these ideas make sense is to ask whether they can be done without the blockchain. Most of these seem to obviously fail this test (eg the government of Hawaii is a centralized institution that clearly does not need the blockchain to mandate a change on any of the islands).
