The main benefit of blockchain is that it is trustless and censorship-resistant. You don't need to trust any business entities. You can transact with someone in a zero trust environment on the other side of the world
The problem is that some people adopted blockchain as some kind of weird gimmick to wrap extraordinary claims such as the ones in the original post and promote scams (altcoins, appcoins, whatever).
That's a problem of anonymity (or lack thereof).
