Did you watch the video till the end ... there is not good definition of "order" so defining entropy in terms of order is just a lazy hack.
did you make the video? if not, describe to me in your own words why entropy cannot be defined in terms of degree of ordering. Did you consider that you can order things in a seemingly lazy yet intentional manner?
The burden of proof is on the people that claim there is a good definition of "order" and that you can define entropy in terms of it.
interesting perspective
