Liberal totalitarianism is not limited to left-liberalism. Capitalism works by a similar logic, supplanting custom and culture by creating "needs" that can be exploited for profit.
In both cases, it works because there actually is a real perceived benefit (at least for someone) and the good that's lost is usually lest tangible. The benefit is usually individual; the loss is usually communal. I am freed from dependance on or judgment by others so that I can do more of what I want, but without any need binding us together and without shared expectations of behavior, there's less to bring us together.
