While this is hardly an important point, I was under the impression throughout these conversations that we'd been blessed by our Guardian. It's a stretch to call Hydaelyn a specific deity, and simply wrong to call it (her? him?) one of the Twelve -- but Oschon (or whoever your guardian may be) is definitely both. I think the original plan for the questline would have expanded upon -- and perhaps even brought some relevance to -- the Guardian choice we made at character generation.
Anyway! On to the meat of the issue:

This was my understanding of it as well, based both on Minfilia's comment about the past being a stone tablet (unchangeable) and the fact that many NPCs, such as the Lalafell from the THM quest line, recognize you in real time after you've been muddling in their memories. And, since you're really and truly physically manifested, you can remove items, thus explaining how we have [whatever it is we get from the Aurelia] in the opening Limsa quest to give to Baderon. However, I'd go out on a limb and say that item is a physical manifestation of that person's memory of that item. Your powers allow you to pull it out of the echo, but it's not (technically) the real item. For all intents and purposes it functions as though it was, but if you have a unique... necklace, let's say, and I enter your memories and then leave, taking the necklace with me, there will now be two necklaces. It's been replicated.
And if you want to worry over the physics of it and the dangerous possibility of infinite creation, we can easily just call it materialized aether and move on. Energy into matter even exists in the real world.

Yes, I think they would. While my evidence is admittedly flimsy, it's the only explanation that doesn't seem to directly violate any in-game dialogue.

As I said above, as far as any observer is aware, I do think we "materialize" an item out of nowhere. And it's been made clear that, as far as any observer is aware, an item left behind in an echo seems to just vanish (or at least cannot be accounted for). Whether it's properly dematerialized or left in some unreachable extra dimension isn't really worth debating. They're the same in application. The other possibility, of course, is the item being left behind in the real past (if we're time travelling), but the musketeers in the past seem no more surprised to see an extra pistol than they are to see a [player's race] standing in the middle of their guild who wasn't there mere seconds prior.
On that note, what do the people around you see when you enter an echo? If they just see you pass out (which is what it seems), then it doesn't support the idea that you're literally stepping back in time. Your body stays in the present, and your "spirit" (or whatever) moves into a new dimension.

If we are travelling to real points then we have to accept than Minfilia, arguably the most knowledgeable NPC about the echo, is either completely wrong in its application, or lying to you. Neither seems overly likely. (Or!! If Catapult is correct, then we can assume the others merely enter memories, while the player is unique in actually stepping into the past. And that's something Minfilia wouldn't be aware of unless she was precognitive-- oh wait.) Plus, there's the fact that the player seems unable to meaningfully influence the past. We could see what the other THM in the quests was up to, but we couldn't stop her until we caught up to her in the present.
In that echo-fight with Emerick during the Limsa storyline, are the outcomes different depending on which NPC we choose to assist?

The very fact that you are experiencing continuity in your echo experiences over multiple people suggests you are affecting continuity itself, not just an individual's memory of it.

You try to tell him Mannskoen took it, which causes you to echo back using ISAUDOREL as the anchor - and when you get there Mannskoen still knows who you are, and when you get back the damn flintlock is STILL gone.
Hold up, the flintlock is missing in the present. We didn't remove anything from the past, we brought it back there with us. It's gone in the now. The fact that it vanishes once tells us that we can take items into an echo (rather than just bring them out as we've already seen), but the fact that it remains missing once we return shouldn't be surprising. It'd be a hell of a lot more confusing if we returned from our second echo and nobody seemed to remember the drama that just went down not ten minutes earlier over the missing pistol.
As for the continuity in being recognized, Moose already came up with a theory for that and I'm inclined to agree -- not being called out as a stranger isn't proof that we've been recognized. If you were talking about something else, I will gladly bite my tongue, but for now I'm still pretty convinced we're not truly time travelling.

While fun for us (I do like to be special) this would be monstrously inconvenient for trying to work out what the echo actually is.
We have scarce clues to go on as it is, if we have to try and split them between "normal" walkers and "player" walkers it's going to double the headache. ...Or be an easy "catch all" for any inconsistencies.
