No, that is not "an inclusion-monotonic sequence (M_n): M(n) ⊇ M(n+1)
which have no element in common".  If {} is in the sequence, what index
is it at?  And what follows it such that M(n) ⊇ M(n+1)?  If {} is not in
the sequence, then you have not shown the example you claimed where one,
rather than my many, empty sets suffice.  I suggest you stop digging.
