You don't need to/probably can't avoid the data brokers, you just have to inject enough noise in to their data to make it worthless. The data brokers are probably the most benign of all of the parties that expose you to security risks.
If you live in a high risk area (like Mexico), and are middle class or above, then you need to do some advanced stuff because cartels have access to things such as your live phone location data.
Ultimately you can't escape surveillance in the general sense. You have a face (probably) and face tracking is ubiquitous and continuous. Google, Bing, and so on crippled their reverse image search for faces, but that misrepresents how good it is.
