Because with humanoid robots you don’t need to redesign the infrastructure to change between robots and human workers. There is less births and more workers are retiring than coming in? Start putting robots on your factory floor. University graduations are up and more peoples need jobs? Retire some robots and hire humans.
It makes the composition of the workforce flexible, able to change in a few hours or days. Refitting a factory to add more non-humanoid robots or to remove them and make workstations meant for humans could take months or years because non-humanoid robots would need vastly different infrastructure than what humans need to work.
