No, you're wrong. Most seatposts are made with setback. The Thompson is just made with setback located in the post rather than in the clamp mech. One could argue that a no-setback seatpost is for when a stock frame doesn't fit exactly.
Furthermore, even if that wasn't the case, you could still be wrong. Maybe the builder designed the frame with certain angles to target a specific feel or handling of the bike, and designed around a seatpost with setback that would accommodate the rider's legs.
Saying that if you need setback, your bike doesn't fit correctly reeks of a) oversimplifying bike fit and b) ignoring a lot of components of bike fit and design.
