It would probably help -- but even the U.S. couldn't afford it. The Thames Barrier in London cost nearly $3 billion in todays money. (A different technology -- but a similar purpose.) It has probably paid for itself in protecting against numerous tidal surges. However, this is a much smaller apparatus than would be required to protect an entire coast; and the tidal surges occur at fairly predictable intervals -- more than once every 6,000 years.

This isn't an exact analogy but how much does a lightning rod cost to protect a building vs the damage a lightning bolt can cause? River floods, hurricane storm surges are known threats and they happen more frequently, a buoyant flood road not only would protect against those known threats but tsunamis as well, at least limiting the damage to the over-topping wave-force. But hey, I'm not going to do it for you for FREE. You want to drown? Go ahead, see your whole seacoast wiped away, I only show you HOW to protect yourself from MASSIVE death and destruction from floods. I'm not Santa Claus, the Tooth Fairy, the Easter Bunny; just an architect coming up with a solution as an intelligent alternative to levees, sand bagging. Instead of moaning and groaning about the challenge, what's YOUR solution?
