Assembling that many parts like each section of the legs will drastically increase the price of this figure from the labor involved. It's already going for realistic, in-depth paintjob, you can't have it all and be at this price point
Originally, these were meant to be almost articulationless, .additions to the Sofubi Toy Box line. But since their sales weren't promising and will likely be over 4000 yen even as soft vinyls, they changed strategy.
This is a middle ground compromise. Having the size and paint of the Sofubi with some free range articulation of revoltechs.
Not to mention supporting all of the weight on tiny joints of the legs could be impossible for some, so all of it being solid is a good choice. There are hornets and giant beetles in this line.
