It is difficult to know the number of Bitcoin users that really care about their privacy most Bitcoin users that care about their privacy are user who are welcome information of the benefit and people who are member of crypto community (like this forum).
If you are going to use a big exchange in the future then you will need KYC. The only other way to get BTC will be on the black market. Would that put you off?
No, for every problem have it own solution and the last time I checked we have p2p exchange site and it is easy to find a buyer/seller on this forum while do anyone make use of black market site which would land her into trouble.
