Clojure is form-oriented so you can think of almost all of its evaluation as sending one form after another to a REPL. In that model of evaluation, you of course want to be able to re-define a symbol an arbitrary amount of times.
The serialization of these forms into a file which has other forms in it is almost incidental. In the case of a file, the forms are passed one at a time to the interpreter. There has been some discussion, iirc, of generating a warning when a symbol is redefined.
