in my own opinion the usa is actually a free country in terms of individuals and they don't care about any individual rights of each person. but if the US government requires everyone to participate in KYC before participating in the cryptocurrency market, then they are actually implementing a greedy scheme to make profits for their government.
I agree with you that the United States of America is the most free country in individual affairs, but if the problem can lead to crime of course any country will not stand still. if required for KYC in my opinion it is not a big problem especially personal data will be protected by the state. After all KYC is a common thing, just like you when you first opened an account at a bank.
