Fully agree with your comment. But it´s not central KYC and public storing of fingerprints. A fingerprint isn't even a fingerprint, it's an electric-resistance scan of deep layer structures. The scan gets hashed, and keys are generated. Its tightly bound to the cryptoprocessors, which most smart devices have. Like secure enclave processor from ARM. Like with a hardware wallet, the information does not come in touch with the SoC of the device or the internet.
The point is having a KYC without knowing the customer. It's only about to know one user behind multiple accounts to solve the abuse problem we see with Steem (I know for many big accounts its no problem but a business lel). We should empower or system by educating the users and adapting new technologies and not by repeating false claims. The wallet technology is even open source. Its a present not a threat. And other chains are possibilities and no competition. Norrowmindednes will harm us long term.
