We call them “desalination” plants, but the salt doesn’t just disappear. The more fresh water you have them produce, the more salt (brackish water) you need to manage as well.

So even while you may imagine the ocean as a limitless supply of water, there’s only so far you can scale desalination.

To be fair the ocean is still pretty big. Also, water doesn’t disappear from the earth…
