Check out the State of Hawaii Department of Health web site concerning vital records under the following: Who is Eligible to Apply for Certified Copies of Vital Records? The Governor of Hawaii is just stating the State’s rules and policies concerning these type of record. By law they are under “Lock and Key”.

Careful now.... depending on who asks depends on what form you get... computer generated COLB is equivalent to CB for most cases. Chances of getting photocopy of long form BC are nill, unless you are O himself. But.... it adopted, chances are zero without a court order.
If the Gov of Hawaii has "sealed" his birth certificate...and if it is in the Dept. of Vital Statistics in Hawaii, then...of course, it does exist. If it exists there, he was born there.
A birth certificate showing birth someplace else would not be in Hawaii's Dept. of Vital Statistics.
To me that is, end of story, unfortunately - and as much as I had hoped otherwise - end of issue. Does someone else have an explanation that would mean one state keeps Birth Certificates of people/persons born somewhere else?
