Maybe we do not have the same idea about what "readable" means, because 
I do agree with you that the code must be readable in all cases. But, to 
me, readability cannot come from hiding complexities away - it means 
finding a proper vocabulary to explain them clearly, as they are and, as 
Nicolas said, as they will bite anyway.
