And I’d point to the evidence of a transfer market specifically for 16-bit ASNs as good evidence of this.

That said, I’d like to understand better the relative imbalance of supply and demand for these resources in the various RIR regions before I form a conclusion as to whether that imbalance justifies a policy change to resolve.
