KYC is a very delicate issue, a lot of bitcoin enthusiasts are against the idea of revealing their personal identity when this is a decentralized protocol, and also the threat of misuse and sale of data.
Btc is supposed to be anonymous and easy but it is neither.
It's supposed to be a lot of other things as well which it is; it is transparent and borderless. It's also irreversible, preventing double spending.
Global adoption would make it easier to own bitcoins without buying them, if it becomes accepted as a currency and means of exchange.
