Their actionable practice is to teach the common man and governors some amount of detachment.
Their metaphysical position, the one the Dao mentions less, is one of a foundational non-being --
"The nameless is the origin of Heaven and Earth",
"What does 'the greatest misfortune is the self' mean? The reason I have great misfortune is that I have the self. If I have no self, what misfortune do I have?",
and particularly nihilist: "Heaven and Earth are impartial, they regard myriad things as straw dogs. The sages are impartial, they regard people as straw dogs." (Straw dogs meaning straw effigies of dogs burnt during holidays.)
I'm arguing that their metaphysical position (not their actionable practice) if followed to the end, with the addition of a modern knowledge of physics and biology and so on, ultimately leads one to a metaphysical nihilism.
The Taoist position is not to have no narrative. It is to apply relentless non-interference to things, people, and ideas that are in our lives. It is only by standing back, feeling unattached, doing nothing coercive, that family, culture, love, hate, beauty, honor, good, evil, and progress arise naturally, so you can experience life to the fullest.
e.g. By trying to force a relationship/family/reunion/ideas into happening, it breaks it, and what was going to be, no longer will be.
