I don't totally believe that you are asking this in earnest.
There is a a lot of truth and a pinch of hyperbole in your answer to the "why the AA" question, but your passion and excitement comes through (for the record, I have no qualms with hyperbole), and excitement and passion is the core of all of this.
I'd counter by pointing out that the Leica AA (currently) exists at a price point that, unless your relationship to money is massively different than mine (and it easily might be), purchasing one would result in immediate divorce (both nuptially and from reality). For me, having a replica is a way to honor some of that design history or feel a bit of the emotion of it. I know that the replica isn't the real thing. I don't think anyone is telling themselves it is. The replica, especially in titanium, looks cool (and was never an option from Leica). You might say that none of those things matter to you and maybe they don't. You might even think my rationale is dumb (and maybe it is). But, I've liked all the LLL lenses that I have. They are fun to shoot...and taking pictures (and having fun) is ultimately the point of the photographic hobby. Your mileage may vary.
(also, you could argue the Minolta 35/1.4 of 1988 is the mother of modern design, at least in how it pertains to the industry at-large from SLR's to modern mirrorless, but that's my two cents...do you have one of those in your collection?).
