The worst is the reality that people could (and would) use it for libelous purposes; such as vindictive exes (no matter the sex), or people with stability problems, or the like.
Nah, it’s not that you “don’t disagree” - it’s just that many of those crypto-anarchist ideas get destroyed when meeting the actually real life.
In this case the easiness of writing fake reviews is what makes it unusable. That’s actually the same reason why decentralised social networks aren’t yet a commodity.
This problem is very well known and is an incredibly popular reason why those ideas don’t work in the first place.
If it's authed all the way down to your SSN, it means that government owns the identities used in the system.
What exactly do you need a blockchain for in such a scenario? Ah right - the unchangeability.
Well, then it means that in all scenarios with the stolen identities we would need to provide for a mechanism to delete the reviews, based on the government-provided data on distrusted SSNs.
In a scenario where we don't allow the reviews to be post-deleted, we are rampantly increasing the value of stealing an identity, which means that the motivation for that goes up a lot.
Now, it means that the only entity that is actually responsible for the correctness of the data in our database is the government.
Now, why do you need a blockchain for that if you could simply have a database backed by the government in the first place?
