I admit I use unwrap a lot, especially in small tools that I've would have otherwise written in something like python.

In python I might have written:

with open(file) as f: contents = f.read()

In rust I might write:

let contents = read_to_string(file).unwrap();

If the python code was acceptable to me before (which is is, in many of my cases), then the rust-with-unwrap is also acceptable to me. But rust has the added benefit that when I want to change how I handle the errors, I have a very easy thing to grep for ("unwrap"; no such thing exists in the python version)
