It's very easy for people who wear pants to live a life where their phone is never switched off of vibrate mode and lives in their pocket. They will never need a noisy phone, and this is how I life my life.
My wife has pockets on about 10% of her clothes, and so typically her phone is in a purse, or on the table next to her. She will not notice it vibrating, thus, she uses the convenient for her feature where it audibly rings. My mother is the same way, but she uses hers so infrequently it simply sits plugged into a charger and works like an old landline. She also uses the ring feature.
Your own issues with noise (which I share many of, by the way) do not entitle you or I to request "mandates" that affect others negatively. The world's a big place and you have to learn to share it with other people.
