The point, as RIPE's "No need" proposal and others have said, is that once the free pool is gone the rationale for conserving via administrative needs assessments is largely gone. The market price system can take over the task of conservation, as it does for most resources.

The thing conserved is not the set of values in 32 unsigned bits, but
the allocations from the set of values in 32 unsigned bits, consumed
by the present, hierarchical routing system, which are capable of
being routed under ordinary implementations of a protocol on
commercially available general purpose routers.

Dispense with the religion, and  focus laser-like on what makes for the most efficient methods of moving IPv4 numbers to their most highly valued use, quickly and with minimal friction.

Define "highest value". Define "efficient".
