If water flowing over continents in rivers is what concentrates salt in our ocean, would a planet that has always been covered in water just be freshwater? The water is just sitting there, not eroding through salts.

    So let’s consider the premise that our oceans got their salt from water washing over the land in rivers after it rains.

    On a world completely covered with water, are we presuming there is a solid ocean bottom? Because if so, that water is “washing over the land” 24/7, isn’t it?
