That’s not true. Most European countries either do or have such extensive regulations to force you to Switzerland who do.

On top of that several tools that have nothing to do with KYC use signed messages, Amboss, nostr.directory…

You cannot make incompatible code to take a feature out unless you want to split the chain.

The only way to get rid of it os by creating something better. Teleporting Bitcoin for example will make KYC by signing irrelevant.
