I agree with David. 
Needs assessment was designed to be a rationing mechanism that filled in the gap left by the absence of a price system for Ipv4 addresses. 
Because ARIN hands out free pool number blocks for free, the absence of needs assessment would provoke a first come first served land rush and subsequent tragedy of the commons. Once you reach exhaust, however, no one gets number blocks for free, everyone must pay a market price for them. The rationale for needs assessment is totally gone. Restricting transfers in this environment _will_ inevitably produce inaccuracies in the registry data.
