I might be weird because I love salt. I snack on it. And butter by itself is not appetizing however melted butter with just salt is delicious. As for pepper and other seasonings you are right. They don't taste good by themselves.
Many foods are delicious by themselves. Fruits, nuts, vegetables, legumes. Some cooked unsalted, some raw.
And in case of those, taste can be acquired. For example unsalted rice at first tastes bad, but when I ate it few times when I was hungry I started liking it.
