Have we misunderstood? It's not about Bitcoin or any other crypto but the blockchain itself. From the beginning of the emergence of cryptographic technology, smart contracts, defi and even NFT, all aspects have changed to be more, safer and of course able to guarantee the authenticity of a work (one of which is Bitcoin = the work itself).
1. Blockchain can change perception a bank or a country, when the price soars and falls again in a matter of minutes it can attract the attention of a country and even the central bank in that country which inevitably bank institutions and goverment will pay attention to ban the bitcoin because of this.
They aren't really banning Bitcoin because of its price? They're banning it cause it's trying to damage their centralized system. A perfect example would be China and its very centralized-centric system.
Maybe one day the real Satoshi appeared and did a patent the blockchain. Is this the real purpose of Satoshi's intention to create Bitcoin?
Will Bitcoin remain valuable or vice versa? for sure Blockchain will still exist and will be a large system that will be used by many institutions and even governments.
Pretty sure it's too late? And he could've done so originally if he wanted to. He had a vision of what he wanted Bitcoin to be using blockchain tech, pretty sure he already had an idea of what it could've been. Even if it wasn't to the level of what we have right now, he should still somewhat have an idea. Besides, I think with how he made Bitcoin itself, pretty sure he had no plans to patent it originally. And even if he did, I don't think it could do anything to stop Bitcoin from being valued by users who see its value.
