(and this is only a partial list of the largest cities that will be destroyed partially or completely as the seas rise worldwide).

Though it is true that people will slowly build seawalls in the richer nations to protect themselves much like Amsterdam already has and other nations will learn from this, there will be a lot of loss of real estate and real financial losses of people who own this real estate worldwide. And in storms many will die if they don't move to higher ground in time as the seas rise to that point.
