It appears you have simply read on wiki that taoists don't worship God and now feel comfortable to use them as a stool pigeon for your atheism. Even atheists bring with them their own flavour of "baroque extravagence", what to speak of the various schools of taoism. . In the mind of an theist, this appears to be a fact. Its not clear what the limits of human design have to do with ideas of design as an explanatory concept. If you want to discuss "perfect design" beyond the human capacity, it seems the first point one would have to introduce is a teleological element beyond human interests, as opposed to a teleological element relegated to human interests. IOW discussion requires a better form than "on the whole, humans have a tough time in the universe, therefore the universe is not designed".
