if you knew history of development of all mighty special agencies(look at ussr/russia, china etc), you would know that you could become of interest to them, even if you don't think you are a threat.

One of the benefits of mass surveillance(for the state) is that people of interest have no way of communicating with the world securely/secretly, they have to assume that everything is tapped and actively hostile to their communication setups.

That means that you could be recognized as a part of shortest path to undermine some person of interest, and there is no reason for you to assume that they will hesitate to harm you and your safety/comfort
