The karst cap is applied at the delta settlement and visible in the river breakdown, which turns a pooling attack into a slow, expensive and publicly visible grind. A single identity may take at most 14% of an epoch's reward pool; anything above the cap is repooled or burned. Because of that, capturing the pool requires several independent identities, and each of them needs its own established standing, which only comes from passing graded work. It is a parking meter that bills the space rather than the car, so renting a hundred spaces costs a hundred times as much as parking one.
