Explanation:
You can do this, and we do. It's call desalination. The process you describe is called distillation desalination, and historically was the only way to turn salt water into drinking water. However, this is getting less and less common these days. Now it is mainly done by "reverse osmosis" where pressure is applied to sea water to drive it through a special filter that separates the salt from the water.
The reason these technologies are not more widely used is because they are expensive. Obviously distillation desalination requires you to boil water, when we're talking gigalitres of water a year, this means a lot of electricity is needed. Reverse osmosis isn't cheap either. You have to pump the water to develop pressure, and the reverse osmosis membranes are always getting fouled and damaged. Roughly speaking, the highest efficiency desalination plants make water at about 10x the price of rainwater collection.
