Why should any body accept that order & disorder are different
quanties?

They shouldn't. Nor should they accept that they are the same.

I assume that you are referring to entropy and the Second Law of
Thermodynamics (SLoT). The SLoT is a statement about entropy. In
thermodynamics, order and disorder are not scientifically defined terms.
They are sometimes used to give students new to the subject a feel for
entropy. As we can see from your examples, because order and disorder are
not scientifically defined, they can be interpreted in often contradictory
ways.

It is manifestation of our pchycology. As a physical quantity there is
no difference.Both are different possibilties of arrangemnt of units


Example:- Drop a glass it breaks to small pieces, even broken pieces,
may look like some from of design for some people. So order & disorder
not necessarily different states. It is how we look at it & how much
benfit they give us



Now Look at Super nova to be a disorder & formation of planets & next
genaration star from supernova to be order. we all know that supernova
& formation of planets is frequent phenomena. Now if order & disorder
are physcical quantities than genaraly order does not come from
disorder it more often incerases with time. How is this ?
So I think order & disorder or not physical quantites which can be
calculated. there are our perceptions depending on how we look at them
