I said "needs accessibility", not "needs large font". Accessibility means that if someone needs to set the font to size 100, they can and the system won't break because of it (e.g. text won't be cut off with no way to see what was lost). It doesn't mean that the default choice is some kind of lowest common denominator that is weird for everybody. The only exception where defaults must be pessimistic are the settings menus themselves. For instance, a button that increases font size must be large enough for anyone to see; a button that changes language cannot be only labelled with the text of a foreign language.
