Right. I agree with everything you said. I was just responding to your remark about that terminus in The Price. The Viidian space probably was big given how long they have been warp capable (I think it was implied a few times that they had a society like UFP millenia ago, maybe in Fury?). It is possible the area we saw in TNG's The Price was within the far edge of Viidian space. We just don't know.
My point was that we can't assume none of the races Voyager encountered during the first two seasons could be found in the area where the Ferengi first got stranded.
OH. Oops.

Sorry, I totally misinterpreted. Thought you were asking how it would have ended up where it was in "False Profits" if it were stable, or something... I was thinking, man, how much clearer can I be?

But yes, I see what you are saying now, and that's a good point. The Vidiians just might have territory near where the shuttles emerged... though actually, come to think of it, I wonder how long those two Ferengi idiots could reasonably survive in their little shuttle once any nearby Vidiians became aware of them...
To be fair, on this topic of the Kazon, invasion vs. exploration, etc... let's not forget that the Kazon were shown to be
extremely unreasonable and
extremely aggressive, at least virtually all the Kazon we saw on the show were those things. Their problems with
Voyager were entirely of their own making.
That said, I don't think too much would happen if a stable Barzan wormhole were being used by Starfleet to explore the DQ. They might attack a lone ship or two, but once Starfleet was aware of the threat they posed, they would simply send ships in pairs, and make sure that non-Starfleet ships had an escort.
Voyager was almost WINNING that fight in "Basics" before the dude blew himself up; can you imagine how even a relatively large group of Kazon warships would fare against, say,
Voyager, and a Nebula? That would be a rout. Whatever threat the Kazon posed initially would dissipate rather quickly, simply on the basis of the fact that they are no match for Starfleet on the whole; as dumb as the Kazon could sometimes be, I think that it wouldn't take more than a couple really bad losses before they began to just steer clear of Federation vessels. And since Starfleet isn't in the business of seeking out those who don't threaten them anymore and giving them a bloody nose for no reason, that would signal the end of hostilities.
Stranded Federation crews, smaller ships on their own that aren't as well armed as Starfleet's, and the like would still have to be careful.
The Vidiians are potentially a much bigger threat. I somehow don't get the impression that they are prone to declaring war on others, but their technology seems to be much more advanced than the Kazon's. And they have shown little concern for the risk they run when attacking a ship belonging to a larger power (that said power could get ticked and declare war on
them), so any lone ships - even Starfleet ships - are potential targets. On the other hand, the UFP might try to offer assistance in curing the Phage as incentive to stop attacking people...
The Krenim... well, I doubt that the UFP itself would become a target for Annorax' crazy quest; being halfway across the galaxy would - one would
think - limit the potential effects that the erasure of the Federation would have on the Imperium. Still, a YOH-type story with a larger scope cold be pretty interesting.
The Hirogen would be a problem from day one, and never really stop being so, but only in the form of isolated, chance encounters. Given the nature of their society, I don't see much potential for any kind of sustained, large-scale conflict. They are just freakin dangerous, even in small numbers.
Species 8472... well, other Starfleet ships wouldn't fare any better against them than
Voyager did. On the other hand, the Borg wouldn't have not attacked them in this alternate reality we are discussing, so they would still play a role. As with YOH, we might end up with a story similar to "Scorpion", but simply with a larger scope.
Since the writers would now have tons of cannon fodder this would go over better with the audience.
Cannon fodder - defined, apparently quite rigidly the way you are using it, as "known, familiar allies getting smashed to smithereens" - is nowhere near THE defining factor in making an interesting, threatening alien race.
Then there's already a positive first impression for all these aliens instead of immediate negativity.
And that, since this is potentially a TNG storyline, no one would have any of the problems they had with these aliens when they were on VOY and would like them all right off the bat.
Seriously? Back to this?
No. The Kazon are
dumb, and were poorly received for that reason. If they had appeared on TNG and had been exactly the same in every way, they would be just as poorly received.
This notion of yours that "the audience" hated everything about Voyager right off the bat simply
because it was Voyager is pure fiction.
