You don't need to. I actually read The Network State first, then The Sovereign Individual right after.

While The Sovereign Individual, I think, is an important book for bitcoiners to read, I would prioritize The Network State.

Others can correct me if they believe me to be wrong in my take, but I see The Sovereign Individual as a warning of what's to come, while The Network State is a potential answer to it.

Since almost every one of us here know what's happening with the monetary system, I'd focus more on potential solutions to the problem, than spend more time on learning about the problem itself.
