> the Dutch figured out how to live with cities below sea level 300 years ago, we'll manage

They also paid for this infrastructure over the course of 300 years on a national level. How this will work for a single city in a huge state in a short amount of time is unclear to me, besides the fact that Amsterdam was built at the end of a bay, which the Netherlands then closed off using floodgates. Miami is facing open water. Lots of open water.
