Well, for example, Bitcoin was an attempt to create a decentralized currency without a "central server" that could be banned or destroyed. People embraced this idea and began to consider Bitcoin as a means of payment even before it was recognized by states.

I would say Bitcoin did more than attempt. Satoshi was able to settle transactions without a centralized entity, which was revolutionary.
People might not like PoW but it was a major breakthrough.
