The features you mentioned in this topic are the features that put Bitcoin in the class of revolution. I also love Bitcoin because of these features, but I love it most because of its portability feature. Nobody knows how much money you have. No one will even know you have money.
Just memorize your seed key and feel comfortable. Nobody can read your mind. This is a great feature.
Hopefully everyone knows that there is a need for a back up for the "brain wallet".. In other words, even though it is fine to memorize your seed, you also better have it written down somewhere and/or some other means of getting at your wallet just in case something goes wrong with your brain.. including walking down the street and piece wood hitting your head.. and then you forgot everything... accidents happen. and memories get messed up.
By the way, the brain wallet can really be good for crossing borders and/or other ways in which you might end up getting searched or questioned... but you still need to have an ability to access your seeds in other ways in the event something happens to your brain/memory between the time that you are transporting yourself from one place to another.. including time and distance..
