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.
I completely agree with what you said, because providing passport data violates that original idea of creating a cryptocurrency. But for this period, the situation in the world is changing very seriously and events are developing in such a way that legally no one can use cryptocurrency in the future until the owners of the funds show their sources of income and provide passport data. I believe that almost all cryptocurrency users will have to come to terms with the fact that they will have to fulfill the KYC conditions.
