Re: Okay, I have a pretty good idea about what is going on.
Also, sorry for being nitpicky on the 'technology' point, but I wonder if humans back in the days were much stronger than their current state (or at least, the humans within the walls.)

Humans were apparently "powerful enough" "back in the days" for that to get specifically mentioned. Of course, this isn't necessarily a sign of more advanced technology in the past, and that there were simply more of them to get things done, especially overwhelming manpower in the production of equipment. Nonetheless, we could also consider a regression in technology due to the Titan crisis. Well in any case, this doesn't really concern the wall-building anyway if they were built with Titans in the first place.
I generally agree with the rest of your post, but I have a bit of an issue whenever R&B mentions "their hometown," because it feels as if it's not really a home, nor is it some sort of settlement (i.e. a town or village etc,) but merely a hideout or whatever. Just pure speculations here.Anyways, the only thing that makes sense right now is that their hometown is somewhere they can return to where they can be safe and there are people they give a crap about. The more I think about it the more I get the impression that people within the walls are just an experiment to make more titans.
