All of those arguments are not new to me, I was for a short time a scan translator myself, I know these "challenges" a scan group faces. Yes, low-quality early scan chaps demotivates the "main" group "responsible" for a particular manga. Yes, it's better to join hands than divide resources and double the work. But, there's a lot, A LOT of "buts" in these arguments. Sadly, I'm not fond of written public discussions, lot of time wasted not only trying to convince the other participant, but also trying to reach all readers of the debate, and the general refuse to concede when found himself not entirely right. When talking more personally, in private, those debates flow way better. So, I will give only a couple of counter-arguments and hoping to not elaborate further in future posts, sorry in advance.
First of all: there is no responsible groups. There is no "law" governing the scanlation world. Of course there's a lot of gentleman's agreement and general understanding that the first group to regularly scan a new title is expected to maintain it. But all this work is illegal to begin with. That's a fact no one can refute, period.
That said, there are people who do not care much for perfectly translated and edited scan. There's a lot of people who don't care. A lot. A- LOT. So, there are many happy guys all over the world who appreciate this work, shitty as may be considered by other many fellows. And the fact that anyone can do a "meh" work (since the fact that there 's no rules concerning it) is per se a "valid" motivation, beneficial for both parties directly involved (the early translator and the happy readers).
Other point is that many times the loner simply doesn't want to be bound to a group, or is simply trying to test himself if he can do a good job without having to wait for an OK of a group who maybe won't give a sensible feeedback. Such loners feel much more motivated to enter a group later when his confidence is high. Sometimes they already know the group responsible and didn't like the management. And sometimes they simply want to share the manga ASAP with as many people as possible. There are dozen of motives, and all comes back to his freedom to do so, since there's no rule concerning it.
I could elaborate much more for reasons why a loner may continue to do whatever he/she wants without even talking to the "main" group first, but I'm gonna stop here. I've said to much already and I frankly do not wish to continue the debate this way, productive as it could be for both of us. Sorry again!
I know you are trying to show all of us the "big picture": the scanlation world could be a better place with more cooperation and less competition. But this special world has different people with different needs. And anyone should complain if a group goes after its own interests in detriment of the rest, since there's no rule to somehow prevent it (the whole point of this discussion).
