How much of the science behind the RDAs have you read? Of course there will be flaws but I've noticed that they tend to be quite liberal with their recommendations.
You're picking out a population where some members have a very high intake of iodine because of kelp. If you look at other seaweeds most of them don't have anywhere near the amount of iodine as kelp does. So there is one edible plant on the planet that is really high in iodine that tastes awful that most of our ancestors never ate and because some of the Japanese population eat it we should then supplement an equivalent amount of iodine? I quite like some seaweeds btw, just not kelp!
Fish on the other hand is an excellent food because it contains a balanced amount of iodine and selenium along with DHA and other nutrients. If you look at the amount of iodine in terrestrial food and the average daily intake of humans through evolution I think 120 mcg will likely seem quite a generous amount. Or maybe early humans did eat the thyroid glands of small animals regularly and have a higher intake than the RDA I don't know.
Pregnant and breastfeeding women do need more iodine. If that woman does have goiter due to iodine deficiency that doesn't mean that the RDA is problematic, many people don't come close to the RDA.
An excellent and tasty way to get iodine is to make stock from fish heads. Fish head stock is known as a healing elixir.

@tim-2 Do you think there is any concern about mercury or other toxins, microplastics, etc. in fish? I have been told by multiple "naturopaths" that seafood is pretty dirty due to the state of our oceans.

Yes mercury is a problem but only in certain species such as tuna which I recommend avoiding. Tuna is not high in mercury so much because of human activity though, it's mostly because of underwater volcanos. Other contaminants only tend to be an issue for seafood caught near industrial areas as far as I know.
Having a blanket ban on all seafood is not treating the issue objectively. A lot of seafood will be significantly "cleaner" than a lot of food of terrestrial origin.
There is an agenda from the highest levels to get people eating less animal products and that includes fish. Just as there is specific propaganda against red meat there is also specific propaganda against fish.
I think it's best to avoid taking any health advice from naturopaths.

@tim-2 I wonder if omega 3 fats in canned sardines are oxidized? I eat a lot of canned sardines so I am afraid too google it.. 😀

Haha, I'm not sure.
With cooking fish in general, long chain polyunsaturates and cholesterol aren't a very good mix when heated, I think the polyunsaturates promote oxysterol formation. In many cultures they sun dry fish, these products are very high in oxysterols.
Cooking is a part of human life though so I don't think there is much point in worrying about it.

A can of tuna is often what I turn to for "fast food". It's probably better than some other options.

Why not can of sardines? Less mercury, more micronutrients...

For me personally, tuna is delicious, sardines not so much... If tuna was not high in mercury I would eat it every single day.

Well eating for taste doesn't work for most people. So that's not a good reason heh.

I think eating for taste would serve us ok, we're conditioned from childhood not to do that though and that creates far more problems.
