What an interesting post! Your well documented and expressed experiences with surgery from the perspective of a patient is very interesting, and I hope you are feeling a lot better post-op! There are many reasons why (unfortunately) Doctors try and 'rush' patients out of the hospital, the first is funding and limited space (An unfortunate consequence of capitalism and governments not funding public hospitals properly), secondly is a psychological one, many studies have shown that the quicker patients leave hospital after major operations the greater chances of a 'full' recovery especially since hospitals are a haven for antibiotic-resistant bacteria such as MRSA (Methicillin Resistance Staphylococcus Aureus) and Finally for comfort, most Doctors, Nurses and staff generally want patients to go home for comfort as this can lead to faster and better recovery in the long run.

I do want to say that none of this is to say that you shouldn't stay in hospital for less than you Feel comfortable with, if you feel you still need it (as you did) then you should absolutely stay until you are comfortable with leaving.
