Not true; loops exist (as a macro) because recursive functions(that naturally correspond to loops and iterations) are harder to read because they hide the logic of termination conditions. Fortunately we are using a powerful language, that lets us transform natural loop syntax to a recursive function.
In my experience you rarely need recursion in Clojure, to the point that it's unidiomatic to use it. For 95% of your looping needs you use combinators, and for the rest there are the loop macros.
The harder part about lisp is actually recursion. Surprisingly, there aren't a lot of programmers who can follow recursion naturally.
(loop exists in lisp but recursion seems to be the common idiom)
