If they can do, I'm sure Florida can too.
That's a nice piece of wishful thinking, but Florida is spending less than 1/10 as much on preparing for / preventing flooding as the Netherlands is. When you compare the size of the affected areas -- Florida has 5 times as much area affected and has more severe geological challenges -- you realize that Florida does not have the will to spend the money. It's not even clear that they have the money. (Certainly there are parts of Florida which are high enough and have sufficiently solid bedrock to be OK; but Miami is not one of them.)
It's also very much not like the agricultural and shipping based cities which are present in major deltas like Bangladesh or Egypt or even Louisiana; those are there because they have an economic reason to be there. Florida has very little industry which depends on its location (yeah, maybe some of the citrus and sugar, but nothing else). It's a bizarre historical accident that it has such a high population. It was a depopulated swamp for most of human history.
The big issue is keeping the water supply systems and sewer systems functioning, and they're at serious risk soon: they're not really designed to be surrounded by the pressure of salt water. Repeated rounds of flooding wrecking the water and sewer lines, and people will go somewhere more habitable -- there's no agricultural or shipping riches enticing them to stay, as there are in the long-lasting river delta communities.
People who think Miami will be thriving in 2060 are simply deluding themselves. Once you get up to Tampa and Orlando, sure, they could be OK.
Sea level rise is finally starting to show up in property values, with low-elevation coastal properties starting to take a penalty. The smart money's already getting out.

Trump's disgraceful abandonment of Puerto Rico after Hurricane Maria resulted in over 400,000 leaving Puerto Rico, mostly permanently. That's one event, and that's a place which *can* be defended. A similar exodus from New Orleans happened after Hurricane Katrina and the failure of the Bush administration there.
One serious failure of the water system in Miami would probably cause a similar level of permanent exodus. And expert opinion is that it's pretty much guaranteed. Septic systems will fail first, so outlying areas will have to be evacuated first.

The Netherlands is spending a billion dollars a year on "water defense" already. Miami-Dade County doesn't even have $3.3 billion to connect septic-system properties to the sewer lines; they're not going to be able to protect the area.

I guess Opa-Locka will go first due to not maintaining their sewer system:

The only scientists who are saying that South Florida isn't doomed... are using politic language. When they go into details, they say that people will have to "retreat". Meaning move inland and upland. Meaning, Miami is doomed.
Well, hopefully Brightline will get that Tampa-Orlando line up and running soon.
