The universe and the laws of physics are "just" reality.
Other things, and especially society, is more like what we make them.
Our society and its functioning is not some god- or nature- handed immutable, it's something that we can change, update, fix, build upon etc (and of course, regress).

Society cannot be endlessly molded to our will because we're not masters of our bodies yet.
