Yes, I am a determinist and a relativist, but I'm not a subjectivist. I am a constructivist and I do have a strong objective principle that elevates the notions of difference, hierarchy, and strength as morally desirable traits. After all, difference is what underlies an objective computational metaphysics. If there is no such thing as difference, there can be no existence at all. One must possess strength to overcome great odds or a cunning enemy, to rise within a hierarchy, to differentiate oneself from the rest.
>in your reality
You mean our reality?
>how is being selfish objectively bad?
First, you need to define bad. I'll define it with an example. The extinction of the human race and all life originating from the planet Earth is bad. How than can the selfishness inherent in Ayn Rand's Objectivism as manifested in Libertarianism be bad?
If all humans followed Randian Objectivist and Libertarian ideals, and focused only on the short-term personal happiness for themselves within their lifespans, and didn't care too much about the future generations, what would drive them to sacrifice their personal liberty to cooperate in a collective effort to counter some existential threat, such as a future asteroid impact that would wipe out all life on Earth? Or the death of our sun? What then will have been our purpose? Do we only exist so that people can consume material goods from the free market until the sun dies, or the Universe winds down in an entropic heat death, and protons begin their decay?
And please don't say that the free market will be able to "fix it," able to reverse entropy.
