In the Tao te Ching, Laozi explains that beings (or phenomena) that are wholly in harmony with the Tao behave in a completely natural, uncontrived way. The goal of spiritual practice for the human being is, according to Laozi, the attainment of this purely natural way of behaving, as when the planets revolve around the sun. The planets effortlessly do this revolving without any sort of control, force, or attempt to revolve themselves, instead engaging in effortless and spontaneous movement.
Several chapters of the most important Taoist text, the Tao Te Ching, attributed to Laozi, allude to "diminishing doing" or "diminishing will" as the key aspect of the sage's success. Taoist philosophy recognizes that the Universe already works harmoniously according to its own ways; as a person exerts their will against or upon the world they disrupt the harmony that already exists. This is not to say that a person should not exert agency and will. Rather, it is how one acts in relation to the natural processes already extant. The how, the Tao of intention and motivation, that is key.
Related translation from the Tao Tę Ching by Priya Hemenway, Chapter II:
The Sage is occupied with the unspoken
and acts without effort.
Teaching without verbosity,
producing without possessing,
creating without regard to result,
the Sage has nothing to lose.
Isn't swilling beer, watching TV, buying useless crap at the mall, and so on, isn't that the most natural way to live in a consumer society? It's effortless, you just punch the clock, buy stuff and simply ignore moral issues that make you uncomfortable. Struggling for any sense of justice, engaging with difficult issues, hell, even doing vigorous exercise routines would seem to be a contrived, forced way of living.
Disrupting the status quo seems to be the least wu wei thing you can do. Going with the flow helps bankers solidify their power, it helps us mindlessly dump tons of garbage into the ocean, it helps police to get away with murder.... The more I think about it, the more the idea seems designed to keep plebeians from meddling in the affairs of the ruling class.
