For simple combinations I agree (maybe 2-long chains with very simple conditions and transforms - but for such things loops are also trivial to read).

But I have seen "functional contraptions of horror" where those functions are both chained and nested which were completely undecipherable by mere humans.

And at least from my personal impression, people who are a fan of this type of functional style are also more likely to create such horrors (which they themselves of course find totally readable and superior to "unreadable" loops) - I suspect that there's often a bit of cargo-culting going on.
