How much of this do you agree to?

The intersection of
a set of sets
is subset to each set in
that set of sets.

The intersection of
an inclusion-monotonic sequence
is subset to each set in
that sequence.

Each non-final set in
an inclusion-monotonic sequence
is NOT subset to each set in
that sequence.

Each non-final set in
an inclusion-monotonic sequence
is NOT the intersection of
that sequence.

Each set in
a 1-ended inclusion-monotonic sequence
is a non-final set.

Each set in
a 1-ended inclusion-monotonic sequence
is NOT the intersection of
that sequence.

Each set in
a 1-ended inclusion-monotonic sequence
with an empty intersection
is NOT the (empty) intersection of
that sequence.

Each set in
a 1-ended inclusion-monotonic sequence
with an empty intersection
is NOT empty.
