The 0th place solution. Since this is a movement excess puzzle, additional space for a bonder is available. It is just not intuitive for it to be a multibonder, but one aspect of area theory is that it contradicts itself.
The reagent has to be suppressed twice for the upper two elbows, which are the main bottlenecks of this other than the half-access unbonder. Otherwise, it is just efficient sequencing of steps with minimizing juggling. The thing that makes a multibonder actually save area is the final bond is able to constantly suppress the vitors reagent, which is unavailable to a single bonder's final bond.
Also note the loading of the final two elbows require the middle hex of the multibonder to move into place, meaning you need to attach the elbows in sequence.
If people were wondering, I did enumerate two track variations of this and each have their own problems they are unable to overcome.
