How is this issue affected by rising sea levels? I'd think that those beaches are doomed anyway and not even sea walls are going to save those houses.

In the long term, you are probably quite correct. In the short term though, the sea-walls give an impression of safety and protection, allowing the owners to sell their properties at great profit before the values collapse.

Here in New Zealand, waterfront property owners have been making legal attempts to block authorities from placing warning notices in the Land Information Memorandum (LIM) documents. These LIM documents are examined by lawyers when a property is being purchased, so to have a warning about your property in the LIM can seriously affect the value of your property.

I am seeing alot of opinions draped as journalism coming from propublica, I tend to avoid that site as it is extremely biased and in alot of cases plain wrong.

Please specify what in this article is wrong. Debate is more interesting and informative than asserts by fiat.

The houses are doomed. Anything built right next to the ocean is temporary, and if you were dumb enough to put millions into a fancy house there, that should be taken as an expensive lesson.

In the absence of seawalls, the beach will advance as the ocean rises, but the loss they're describing is far in excess of anything caused by sea level rise.

Whats the alternative to a sea wall? Beach reconstruction? Let the water reach the houses?

Probably all three, if you include sand pumping. (I guess that's beach reconstruction said another way)

Hawaii might be different to the continental shelf abutting changes i see here in Oz. Its driven here by a northward sand flow, combined with erosion. Sea walls and groynes and channel guides and dredging for river access are a dastardly trio which wreck the natural beach as does building on sand dunes.
