Everything extremely bad for you is not always a diuretic. Sometimes, it's a deadlyetic. You have to consider that we have fat/oil and water solubles. Your urine just can contain the water solubles. The next question is, why do you compare eggs with potatoes? Both are round, I know... A lot of animals drink their own urine. Hamsters and Guinea pigs are known to eat their solid feces, dogs are known for this behavior, sometimes, too. The apes do this. So did and does the human too. May it be because of some (traditional) medicine believes, Emergencies like in the sea, fetishes or other reasons. Since a long long time. In each culture and nation. I'm sure one of your neighbors does this too :) Where exactly is the evidence for urine being bad bad bad as you say? Arsenic and alcohol are known to kill, but urine never has been used for killings or something like this. There are quite a few studies around that topic, why don't you just Google first instead spreading misinformation? May be you start with this here: https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3032615/ https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3032615/ It's the first Google search result I could click the fastest. There it's written what you should know to reposition your beliefs. One thing I can tell you without spoiling: you can't piss that much you can drink. We loose some water through sweating and by respiratory means ... So it never will be fecesdynamically feasible (the 3 laws of fecesdynamics: eat shit repeat)
