KYC and BTC are diametrically opposed concepts. One advocates privacy and non-stalking, while the other aims to reach out publicly to their credentials. Yes, you can use BTC without KYC, but most bounties or similar charities will be abused because KYC is a requirement.
Can't put it any better than this. One of the reasons why Satoshi invented Bitcoin was to give an additional layer of privacy for the users. And with KYC becoming mandatory in the exchanges, user privacy has become a thing of the past. The good thing is that users are still finding loopholes to avoid KYC, such as using multiple exchanges and withdrawing/depositing amounts below the KYC threshold.
