Iodine deficiency leads to goiter in adults and cretinism (decreased height, lower IQ and in some cases mental retardation) in infants and small children. Many places can get enough iodine through vegetables, but many places cannot. The small amount of added iodine in iodized table salts are typically not enough to cause any issues but are enough to backfill any nutritional deficiencies. There's no value in demonizing something you don't understand. Let people eat their salts. There's no harm in unrefined salts, but normal table salts should likely be consumed occasionally by almost everyone.
