If Satoshi got everything right, then why is bitcoin still being developed? The whitepaper also talks about one-CPU-one-vote, but nobody mines on CPUs anymore. It talks about "a single hash" for mining, when we actually use a double hash. It talks about following the "longest chain", when actually we follow the chain with the most work. Just because it is in the whitepaper doesn't mean it can never be changed.

The whitepaper also says "privacy can still be maintained by breaking the flow of information in another place: by keeping public keys anonymous". We no longer keep public keys (or rather, addresses) anonymous. Every centralized exchange and service links every deposit address you use and every withdrawal address you use to your real name and KYC data, as well as tracing these addresses backward and forward another several transactions. We have entire industries built on de-anonymizing public keys and address and selling their services to the FBI and others. I doubt Satoshi foresaw that.

But none are as widely accepted as bitcoin. As long as I can keep using bitcoin privately then I will continue to do so, but as I said above, if the day comes when I can longer spend my bitcoin without a centralized third party invading my privacy or demanding KYC, then that is the day I stop using bitcoin.
