It is impossible to achieve complete confidentiality, even if you completely try to do it. If you will be very much needed, for example, the FBI, then they will find you, you can not even doubt it. The example of the silk road is very indicative here.
Basically, if it relates to the internet there will definitely be loopholes to reveal secrets. If you really want privacy, go to the cave, live individually, don't use the internet. Of course, it's not a wise choice because we will miss many good opportunities from the advancement of civilization. Actually there is nothing that needs to be covered up, privacy is indeed the rights of each, just relax if we do something legal then there is nothing to fear from government supervision.
