I understand how tempting it is to simplify the somewhat complex matter of expansion, but it's not possible. Preventing commercial fishing, deep seabed mining, and other industrial-scale extractive activities is only one of the reasons hundreds of thousands of people supported expansion. Providing a pu'uhonua for tunas as the fish move into the area with warming is another. Perhaps most important and relevant to monument designation are the absolutely amazing and unique natural, cultural, and historic resources that are recognized. 

With regards to funding, funding for protection and management is never guaranteed given political priorities and whims, but it is more likely with monument status than without it. 

This is the truth about the expansion you seek: mass support to officially recognize, honor, and protect a large marine environment for its many values and significance. Only time will tell if we succeed, but I'm convinced expansion is a move in the right direction we must go.
