Hawaii has an abundance of underutilized land through a combination of bad zoning/regulation (anti-market violence) and civil rights violations ( Hawaiian 'homelands' which reserves much public state owned lands to only people 'of the blood of the [right] races').

The housing issues are at best partially caused by the rich; plenty of places to put a cheap tar paper shack but for whatever non-market reason you cannot.
