Well, yes Fuzzy Logic can do everything that boolean can do. It just has more states. I won't comment on people's default assumptions however there was nothing to be assumed here since in the original post it was explained that he was using 16 states. Since it was explicitly stated, we need no assumption. Your reply here is referencing a use case in which I had created a partial ALU (didn't have adder/subtractor, only logic functions as I was tinkering with a 4 bit adder using comparators at the time and didn't complete it), also a use case is exactly what the original post here is about.
I am not sure how usage cases outside of the post would be relevant unless they were directly related however you could image a general purpose ALU based on 16 state logic which would be programmed to check outputs of some device (a chest that is part of a sorting machine for example) and then take action on the output (allowing a drain of the chest before filling to prevent the hopper from backing up and ruining the sorting functionality for example). In this example, yes you can do it without a computer and yes you could do it in boolean assuming you convert the output of the comparator but it is just an example. Like all logic devices, the limitations are based on how you can use the signal to interact with other hardware and your imagination.
