Maybe so but it's still worth remembering that there is no secure blockchain without the value inherent in the token "bitcoin"
They are inseparable
Yes, I don't understand why people can say the currency function has a less bright future than the blockchain when all the security of the blockchain actually depends on the value of the currency, because it triggers the motivation to mine and secure the network.
Of course the blockchain technology can be replicated, but any replication will be less secure if there's less value attached to the replication.
I think the relationship between value, security, and usage is in fact self-reinforcing:
more security > more
^ usage
more value <
ya.ya.yo!
