The Federation "allows" the Klingon's to rape, pillage and slave.
Absolutely no difference.
Backward ignorant aliens are allowed to be backward and ignorant. Their backward ignorance is cherished. That's the Prime Directive. Changing backward ignorance creates a responsibility of consequences and a duty of care which is possibly never ending... Iraq any one?
It is law abiding for the starfleeters to let aliens handle alien matters in alien space.
The Kazon were the recognized power in that area.
It was their home.
Caretaker was a senile hobo drifter trying to be a god in Kazon space.
No wonder the Kazon had no patience for arrogant condescending blow hard aliens.
The deal fell apart before it had a chance because Janeway backhandedly called their Maje "uncivilized".
It was never said that the Array was not an option. the opposite was said over and over again in fact.
Tuvok was prepared to use the array to go home because he figured out how to use it and he would have until Janeway decided she should shit on the Prime Directive because her heart had not yet shrunk into a nugget of coal.
And then there was B'Elanna, a woman who was to be the chief engineer who was mighty pissed about her magic door home being atomized by a mere starfleet captain...
JANEWAY: I'm calling to warn you to move your vessels to a safe distance. I intend to destroy the Array.
JABIN [on viewscreen]: You can't do that!
JANEWAY: I can and I will. End transmission.
KIM: They're increasing fire, Captain. Shields are holding.
JANEWAY: Move us four hundred kilometres from the Array, Mister Paris.
PARIS: Yes, ma'am.
TORRES: What do you think you're doing? That Array is the only way we have to get back home.
JANEWAY: I'm aware everyone has families and loved ones at homes they want to get back to. So do I. But I'm not willing to trade the lives of the Ocampa for our convenience. We'll have to find another way home.
TORRES: What other way home is there? Who is she to be making these decisions for all of us?
CHAKOTAY: She's the Captain.
TUVOK: The tricobalt devices are ready.
PARIS: We're in position.
JANEWAY: Fire.
Seems to me here, that B'Elanna is really pissed that Janeway is taking the only way home they got off the table, and that interest int he array is not any trick or diversion at all.
Hells, 5 years later in Night she was having an emotional breakdown because she finally calculated that it was a mistake to destroy the array and that they should have used it to go home.
ANEWAY: I believe so, but there's a catch. We'll have to collapse it from this end, where it's dimensional radius is weakest. We'd be closing our short-cut out of here.
CHAKOTAY: Two more years in the void. I can live with that.
JANEWAY: But I'm not sure I can. Four years ago I destroyed the Caretaker's array to protect the Ocampa. That act of compassion stranded this crew in the Delta quadrant. I'm not about to give that order again.
CHAKOTAY: This situation is a little different.
JANEWAY: It's close enough. I'm asking this crew to make too big a sacrifice. I won't make that same mistake.
Bazinga!
