This seems to be a controversial option but I think any item that helps the body function in a basic way when the body cannot physically perform that function by itself should be free.
Eyesight should be free.
Going to the toilet should be free.
Mobility should be free.
All of your internal organs functioning in a normal way should be free,
and yes this includes medication.
Sometimes our bodies can’t do certain certain things either as well as it should, or at all.
Without those things, our quality of life decreases or even worse, we die.
I don’t think there should be a cost attached to just being alive.
