I'm going to object to your argument, my objection is that immersion is fun as well. And being able to buy plate armour at an improbable price (yes, let's stop the discussion about what was real and not real, it's all about what *seems* real) hurts immersion.
Conversely, speaking for everyone in my group, having one of the basic armor types cost WAY MORE than the one right below it on the list (3e) ruins our fun because we wanted to start with the plate armor we were planning on using for our character.
Different groups have different ideas of fun.
