This is my main opinion too about the ending. Over 4 years of war, occupation, death and every other bad thing to happen. Steak, clean air, do what ever I want. I'd probably ditch the mechanics too, Besides the Battlestar was almost a total loss and the other ships were badly worn through as well. I think for the survivors of Caprica it was time for a simple life, let future generations decide if they want to be more advanced, As Lee said "We end the cycle and start over."
Sometimes with the way our current world is, Living life a few hundred years ago sounds tempting at times.
