What gives bitcoin the characteristics of immutability? What is it that makes it unchangeable? The first answer that comes to mind for most people is "the blockchain." The blockchain makes bitcoin immutable because every block depends on its predecessor, creating an unbreakable chain back to the genesis block, and if you change something it would be noticed. Therefore, it’s unchangeable. That is the wrong answer The characteristic that gives bitcoin its tamper-proof capability is not "the blockchain”; it’s proof-of-work.” ― Andreas M. Antonopoulos, The Internet of Money Volume Two
Bitcoin is the internet of money
The open blockchain will change this world
open, public, borderless, neutral, and censorship resistant
This system requires a mechanism by which the network can be secured.
Without a cryptocurrency ?
This mechanism is at the heart of making the system secure. Without a currency you can't handle security, you need a central authority to decide if a transaction should be included or not. At that moment it's no longer open, borderless or censorship resistant. It becomes completely useless.
just because it s blockchain doesn't mean it doesn't have limitation

Privacy related coins : like monero z cash
Resource sharing blockchain : where you can buy or rent [computer power], storage or network bandwidth
An atomic swap is a smart contract technology that enables the exchange of one cryptocurrency for another without using centralized intermediaries, such as exchanges
Atomic swaps can take place directly between blockchains of different cryptocurrencies, or they can be conducted off-chain, away from the main blockchain
Human civilization flourished in times and places where sound money was widely adopted, while unsound money all too frequently coincided with civilizational decline and societal collapse
