"Sea Salt" over Plain Iodized Salt?

For professional dieticians: is there any TRUE benefit of using 'natural sea' salt, rather than plain 'grocery store' iodized salt?

One of my friend's Mom is a nutritionist. I asked her this question, and, I quote,
"Nutritionally, there is no benefit to using sea salt over rock salt found in quantity in grocery stores.
What little trace minerals found in sea salt don't amount to anything, you get more from fresh foods. Unless one has an Iodine allergy, iodized rock salt is far more beneficial than sea salt.
The ridiculous price that is charged for "natural" sea salt is one of the biggest frauds perpetuated by the "health food" suppliers on the public."

rock salt and sea salt taste different
some sea salts are Kosher too if that matters.

Even as a non-professional, I can tell you that there are other minerals and salts inside sea salt.

Depends on the individual. If you are iodine deficient, table salt is a means to increase your intake.

Sea salt provides natural iodine in trace amounts, preferable if you do not have an iodine deficiency.

Not a professional opinion, but, from what I understand, salt is salt, whether it's dug out of the ground or processed from sea water.
"Specially for the idiotically inflated price stores ask for "Sea Salt"!
