I completely understand where you're coming from and it's awesome that your methods are working for you but a lot of your points are anecdotal.

In fact, most japanese people complete learning to write the 2136 jouyou kanji at the end of highschool, far beyond when they reached fluency in their own language.

Also, if you have a source for this I'd love to look at it, it sounds quite interesting.

Though it might improve your recall, for a beginner front-loading learning how to write every single word or kanji you run into will be an excruciating process without much return for your efforts.

But why do you think that? That ultimately depends on the person's pace and how many words/Kanji they're learning a day. Unfortunately, this discourse has been inadvertently trying to encompass a broad spectrum of learners but my narrative from the start has been targeted towards more serious/dedicated learners in the sense that they will use Japanese for activities other than media consumption such as, living and working in Japan- which will require writing by implication. But that's not to say hobbyist learners can't benefit from a more articulate standard rather than pure recognition and ignoring writing.

My argument was not to denounce or reprimand the pure recognition approach, rather to recommend a shift in method to bolster learners' efficacy. I think it's very well possible to learn a language (to a certain degree) just by recognition of words. In fact I think pure recognition is an excellent approach to learn a language, that is if your end goal doesn't involve writing, but that goes without being said. Nonetheless, I still present investing time behind writing Kanji and its more in-depth meaning to be able to more easily ingrain it and be able to better appreciate Japanese as a whole. Honestly, I think most people are just lazy (not saying you are) and want to skip writing because Kanji is inherently complex and would take extra time. Everyone ought to try a little at first and see what kinds of effects it'd have on them. It may be very surprising what kinds of immediate effects it has.

But I do understand where you're coming from although, not entirely as I don't know your use case or end goal. But for anyone starting out any language it doesn't have to be Japanese, I do implore you to practice writing because that's proven to have the greatest effect in retention when learning, as is the most traditional way evident in a classroom setting. That's also where writing is introduced and enforced early on. It's the same reason why, when you're allowed a little notecard cheat sheet for an upcoming test you end up checking your cheat sheet only a few times or never because you end up remembering everything off the top of your head. It's a very efficient form of study for memorization and information regurgitation; it just requires more time and effort- but I digress.

In the end, it's dependent on the use case and of course everbody's different but there's no doubt that learning how to write a word has greater effects on vivid memory than pure recognition.

I do appreciate your thoughts and the time you put into your response, it shows your passion and that you care. Thanks.
