Well, that depends on what you are out to do.  In particular, if the difference 
is forced by the nature of the notation but not by the facts on the ground, 
then, indeed, there is not a need to make the distinction.  If you have 
something else in mind, then there are always C-sets and all that they entail 
(most of it with little direct relevance to real life).  On the other hand, 
mathematics (though supposedly possible) is hard to do with L-sets.

Surely there is a need to distinguish {a, b, c} from {{a, b}, c} in ordinary 
language and thought, where "{}" is some kind of group with members.
