You might be right in the first part, and the "fear" of s-expressions are only expressed as a fear of parenthesis.

But on the second part I think that's the same as for most languages. You end up with nested scopes at the same degree as any c-like language really. But most lisp programmers tend to break out into new functions a bit earlier than let's say JS programmers. I'd argue that normally you'd have to keep track of less depth in a normal Clojure program than you would in a JS program, simply because of how a programmer usually works in those languages.
