If there is a subset of instances of A that are isomorphic to all the
instances of B, then it is reasonable to say that A is more complex than
B.  This is not a full answer (there many be other factors that people
consider important to "complexity") but it does answer your initial
question about why trees are considered more complex that lists: a
subset of trees is isomorphic to the set of lists.
