You can't ensure everyone follows the same moral code without violating NAP

This is why Decentralization is a thing. Go to a jurisdiction that socially share your morals. We do this today.
I'm not hanging out near drug dens during the day. I'm not trying to find friends at the local pub, since I'm not a drinker.
If hippies want to have their socialism commune, buy some land and farm all day. I don't care. The point is that I can justify an AnCap viewpoint, secular AnCaps cannot.
That is exactly what I claimed/defended in my OP.
Its not the same, the OP is arguing that whatever is socially acceptable in an area is what "is moral"
I'm saying, if people want to live a certain way, moral or immoral, go do your own thing. I'll be a part of my community and if you want to be a part of it, develop Virtues.
My issue with it is that you can never be sure to be following the One True objective morality. So even if it exists, it hardly matters since everyone would interpret it subjectively.
