No, those rules are about protecting me from my neighbor. They're perfectly reasonable, both as timeless moral norms and as law.
The problems begin when I want to control my neighbor's behavior in ways that have nothing to do with protection. If I feel the need, for example, to prohibit him from having a gay relationship because it's against my religion. Or telling him that smoking one plant is fine, but if he smokes a different kind of plant I'll call men with guns over to his house to stop him.
That is what I mean by moral authoriarianism.
This is an innate aspect of society. See: murder, sexual assault, etc. Morality is a human construct.
The real question is where to draw the line, and the answer isn't immediately clear, even in a court of law.
I do agree with you though that moral conservatism needs to move on from the 1950s.
