If freezing salt water produces freshwater ice, why is desalinization such a difficult problem?

I was watching the above minute physics video, and they indicated in a brief one sentence line that saltwater freezes into freshwater ice. That got me thinking.

Under what circumstances could you actually freeze salt into ice? To make salt ice?

    Air dry it for table salt?

    It’s essentially how we make sea salt, just gather seawater in ponds and let it evaporate.
