I think you underestimate the meaning of the word 'inconvenience'. Hot water is a convenience.

My point is that your list is one list which you are making, but someone else could look at your life and make a different list. Your argument only goes so far you can extend into your own life. If you really cared about something's place in your life, you wouldn't classify it as a convenience, so you are conveniently applying your own classifications to other people's lives, which you don't have a right to do.

This is why we have democratic institutions and authority -- to make these limits about what is tolerable and intolerable -- not what people's conveniences are.
