Almost all of these would have been possible without a blockchain. Either through a web of trust or even simple cryptographically signed messages with timestamps stored in a normal DB. Some of these aren't even "real world use cases" like Hawaii trying to boost tourism by something-something blockchain.

Civil is a notable exception, though I'm not unconvinced that it couldn't be done without one.

In the end though, if blockchain is sexier / more marketable than signing messages with GPG or SSH keys then fine. At least we're getting higher integrity guarantees on data one way or another.

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.

Agreed.

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).

Even if these were all full-fledged businesses/ventures/operations -- most of them don't answer what is, to me, the real question of the day: in what applications are the benefits of blockchain an actual imperative to the use case? Most of these don't seem to clear that hurdle.

Namecoin is the best example of a real world use case, a proper replacement of a DNS with no central authority. This is clearly one which is very difficult to replicate reliably without a blockchain.
