Your response misses the target the parent was getting at. There are laws that constrain behavior in public places derived from the taboos of the past. This is what you are referring to when you talk about limits to nudity and such. These laws may derive from shame culture of the past, but they have modern relevance largely due to the existence of laws. There's another form of shame culture that isn't codified into law but constrains behavior due to the potential reduction in social status for breaking various taboos. Essentially part one's feelings of status is sourced externally and this provides a moderating effect on one's behavior. The problem is that modern society has seen a stark reduction in the effectiveness of this kind of shame culture. We've essentially devalued the prevailing culture in favor of various sub/counter cultures. Now every degenerate interest has a sub-culture formed around it that insulates anyone who identifies with it from the shame of going against the prevailing culture. The usefulness of shame for reinforcing social norms has been eliminated to disastrous effect.
