(personally speaking, like many people I have eczema, and my wellbeing tends to be diminished by having a scraped anus)
My mother has heart issues and she has a pump that's connected to her 24/7. She has a medical condition and so has special needs. I would not call that pump an essential but it certainly is essential for her.
The context of this conversation has been _in general_, my responses were never meant to apply to those with medical conditions.
to answer your question, a bidet is a nice to have, a toilet would be an essential otherwise you're shitting in the street, as you implied about downtown SF. Because toilet here does not mean literally toilet, but someplace reserved for using the restroom. When I go to the river to fish they have an outhouse there and I absolutely use it, as do construction workers with the mobile outhouses they employ.
defecating and urinating are absolutely essential activities, how you clean yourself afterwards needs to happen but any specific way of doing it is not essential.
But doing them in a toilet is not, unless we start expanding the definition of essential to include dignity and thriving.
buuut... well you know your response is bullshit.
hey guys, dontcha know the only essentials are death and taxes! otherwise you have to admit that a brand new car driven off the lot is also an essential!
yeah, ok...
You may try and argue some of the grey areas, but most of the things you listed are _clearly_ not essential, they're desirable by specific people, as you said.
