I'm assuming it's that your raiding party are the people you do direct action with, and having a seamstress among you is super useful and important because they can not only create and mend clothes and other useful items like blankets and tents and banners, but in a real bind they could potentially sew up a wound, too!
This reality is a simulation. But it's not electronic like the Matrix, it's social. You've been socially conditioned to see what the owning class want you to see.
