I don't think it's such an rare adversary to have. Organized crime can easily have several experienced hackers in their "organization". It's common knowledge that gangs actually do monitor peoples routines who are inside their territory and they do it for several reasons, one of them being to rob your apartment or do an evil maid attack on your computer.

It's also common knowledge that all adversaries view people who have higher security than the average person as a person of interest or a mark. If they are spies they think you don't need privacy if you have nothing to hide and if you are trying to hard to hide then you must have something important to hide. Criminals think if you have security then you must have something valuable to protect.

Also some of the methods described her this thread seem impractical and extreme but one you go down this rabbit hole of security and privacy, you become used to gradually putting in a little more extra effort for better security and privacy. Normal users can't understand how someone can survive with having to toggle scripts on/off with the noscripts extension but for most people who are interested in security and privacy that is easy and effortless like breathing air.
