Apart from the convoluted 3 precepts in the OP, objective morals cannot exist because at the end of the day, a (subjective) mind is needed to make a decision about moral precepts.
For example, if I say that stealing is wrong, where do I get that moral precept from? Experience? Some unspoken authority? It doesn't matter if it is either, because after both considerations, I have to decide for myself if I want to follow the moral precept, meaning I have to decide for myself if it is a moral thing to follow, a given authority or simply experience notwithstanding.
This is why I say that people are moral regardless of what authority says, because it's an wholly internal metric, regardless if you find it in a book or if you have arrived at that conclusion via experience. I just think that getting there with experience is more valid than if you just get it handed from some external source, like an authority.
