Refuse, ironically, becomes the only artistic ending by making you lose for taking a moral stand. It makes you realize that standing for your convictions does not automatically result in victory. It is the only ending that isn't rainbows and sunshine (which the 3 other endings have become). It is the only ending that is actually a bittersweet ending.
It is also, of course, the result of a utilitarian calculus
the same as the other endings that also requires either a "leap of faith" as OP put it
or metagaming to perceive the conclusion. In refuse, the entire current cycle is sacrificed for the greater good. In destroy, all synthetic life is sacrificed for the greater good. In control, Shepard is sacrificed for the greater good. In synthesis, all life's
current state of being is sacrificed for the greater good.
There is no greater morality to refusal than there is any other choice, only what
you put into it.
At the time you make the choice, there is no guarantee Liara's beacons will survive (only her word, based upon her
immense skills as an information broker and archeologist), that the next cycle will discover those beacons if they survive, or will have any way to access or interpret them properly as the "current" cycle was unable to properly interpret the prothean beacons -- without the Thorian you conveniently killed in ME1.
After all, the female Stargazer scene is extremely ambiguous in this respect. One possible interpretation for the scene is that they found and accessed the beacons, but misinterpreted it and
think the previous cycle defeated the Reapers. "Their sacrifice they made so we can live without danger" and whatnot.
