It seemed like a waste of power to me. Remember that replicator usage was rationed on Voyager (except for shuttles and stuff like that).
Actually, not to be a hater, but I don't remember that. I remember them briefly mentioning this in the first season, and randomly again in later seasons, but aside from them using the mess hall I never saw rationing on Voyager.
I'll never forget that one episode where Torres was stressed or whatever, and Neelix, in an attempt to cheer her up, goes over and replicates a thick stack of bannana pancakes. Torres walks away without touching them, and my wife literally shouts at the screen "I guess they've got a lot of energy if they can replicate food and then throw it away uneaten."
That episode where they gave away three or four shuttles to those telepathic refugees was also a great example of their lack of need for resources.
And I never bought the excuse that it didn't cost them energy to run the holodecks. Keeping off the holodeck should have been order #1.
As for the uniforms, I honestly believe the show producers didn't want to shell out the clams for making new duds for each crewmember. There's your rationing.
