It is one of our strongest desires. Lust for pleasure, our attachment keeps us in lifetimes of lust for life on the Earthly plane. But our primary Drive is that of completion, the experience of and the understanding that fulfills all of our journey: within the center of our being that experience of the living God within. All and good but all of that is covered by the illusion of our Egoic desires on the physical plane. that's where Freud was.
It's just plain hard to brave the dissipation of the weight of the ego if only for a while. Spirit never dies!

From a professor at Tulane (Michael Keyes, M.D. Psychiatry) on Quora: Freud did the best he could with what he had. He was constantly upgrading his ideas and in the end his idea of psychoanalysis would have barred him from present day Psychoanalytic Institutes (his last patient was declared finished in six weeks.) What happened after Freud was an explosion of hypotheses all riffing off of his ideas. Some were brilliant and have lead to significant therapeutic advances and some were total whackadoodles (the schizophrenogenic mother, for example - I was asked about that concept in my boards by the originator; I told him it was unscientific rubbish. He was not amused. I passed anyway after they took him out of the room.)
All in all, in spite of his delineating no scientific theories and his practical ideas being inefficient, Freud made a seminal contribution to the understanding of the human mind and brain. His was the first world-wide revolution in the care of mental illness and it lasted over 50 years.
