As far as we know, nature behaves unpredictable.

E.g. we cannot predict the path, a certain fly would take.

So, why should nature like to predict experiments?

I would exclude the requirement of usefulness (as means of predictions) 
for a valid theory about how nature behaves at a fundamental level.

Instead it should be simple, since nature would not use too many 
different entities, but infinite variations of the same in different 
manners.

The best theory possible would use only one something, that is observed 
in various guises, as stuff, fields or empty space.
