But Blockchain cannot exist outside of cryptocurrencies. It's a system where popularity of a cryptocurrency is crucial for blockchain's security. So if it can't succeed as a cryptocurrency there is no blockchain to talk about. And once it succeeds we can start solving hard peer to peer trust problems with it.

The use of cryptocurrencies within blockchain is to "promote" the adoption/distribution of a system. However, there are other cases where the stimulus for the adoption is non-monetary (e.g. access to the information) and thus a crypto-currency is not needed.
