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?
That is a really good point! I wonder if this means the polar ice caps have saltier oceans… but I’m guessing the brine is denser so it stays on the bottom.
