I align with your thoughts, i think that the best place to store such important information like your seed phrase is in your brain. No matter where you are or where you go in the world the phrases will not depart from you. So in this regard if a person decides to memorize their seed phrase, i think that it is better to get a wallet with twelve phrases instead of twenty four, so it'll be easier to memorize. All the person needs to do is to look up on the seed phrase, once in a while, in order not to forget. This method does not in any way undermine the importance of storing the phrase information in other secured locations, but just to be on the safest side, after hiding the seed phrase it's better to memorize them in the brain. As a matter of fact I'll start to memorize my seed phrase from today.

In the event of war, fire disaster, natural disaster, theft, or misplacement of where we stored our seed phrase, it can damage or be stolen, but the ones that are stored in our minds can not be stolen or damaged. So in case where any of the things mentioned where to occur and the phrases are lost all we need do is remember them from our memory, them rewrite, hide and start to memorize them again once in a while.
