Isn't Zillow ignoring the immense value created from all those new beachfront properties?
I wonder if there is a long term business model here... Invest in land and prepare it to survive being surrounded by water, build infrastructure etc and then sell it to the same type of people who buy bunkers for end of the world situations.
Kind of makes you wonder why we haven't already been doing this on areas just off the current coast. Guess that old saying really is accurate -- necessity is the mother invention. Dutch Docklands is one of the companies building these new facilities. Their mock ups [1] look amazing.
