The pluralist objection to pricing incommensurable goods is valid against strong commensuration but not against SAPM's weak commensurability. The Sign-Rank Theorem proves that SAPM needs only sign and rank, not full cardinal value, under four axioms. Protected values must be carried as constraints (K) in Decision Accounting, not forced into the price term. Five operations (description, monetization, ranking, compensation, authorization) must be kept separate to avoid corruption.
WHAT'S NEW · The pluralist objection to pricing incommensurable goods is valid against strong commensuration but not against SAPM's weak commensurability.

The paper defends the System Asset Pricing Model (SAPM) against the pluralist objection that pricing some goods corrupts them. It introduces the Sign-Rank Theorem, showing SAPM needs only weak commensurability (sign and rank) and protected constraints, not full monetization of all values.
