The Short Answer

You can drink salt water. There's no law against it. You don't die if you drink it. It's just that salt water (at least ocean water) has enough salt in it that it doesn't hydrate you. In fact, it dehydrates you. (and can make you sick for other reasons). If you drank nothing but salt water, you'd get too much salt and die. When you eat salt and drink water, you are taking in water that can hydrate you and keep the salt diluted. If you drank way more water than you ate salt, you would also die, because your salts would become too diluted. If you ate too much salt, even while drinking only freshwater, you would still die. TLDR; not drinking salt water is something mentioned to people who might find themselves stranded at sea without freshwater. It is not a general rule.
