Second, example 2 produces less GMV growth but more profit, which is the trade the operating-layer-aware seller is consciously making — they are leaving GMV on the table that costs more in margin to capture than it produces in profit, and they are reallocating that capacity to higher-margin operations. Third, example 3 illustrates the asymmetric exposure: under a plausible 2027 ad-auction inflation, the example-1 regime becomes unprofitable on the increment, while the example-2 regime stays profitable because the true-ROAS pruning is itself a buffer against ad-auction inflation.
