While I agree with you in general, sometimes less code can be harder
to maintain (when it is more difficult to understand).

Some time ago, we had a (quite heated) discussion here about
a one line signature transform involving a triply nested lambda construction.
It was not difficult for me to understand what the construction did;
however, the original poster found it very difficult to grasp.

Often, functions returning functions are more difficult to understand
than "first order" functions (those returning simple values only) --
at least for people not familiar with higher abstraction levels.
