It's easy to say, but try imagining how macros will be written when there are no parentheses. I think the parentheses help a lot in lending homoiconicity to Clojure and other Lisps. Moreover, when you use a decent Lisp-aware editor parentheses usually vanish in thin air. All you care about then is the indentation.
