Assembly has some up-front overhead costs, but at present, so does

The overhead of orbital assembly is more than up front, but continues
throughout the assembly operations phase is the mission is of any
size. You take a performance hit either per launch in the form of the
rendezvous and docking hardware, or across the whole pipeline by using
an OTV.
