As I have said, there is no such thing as an inalienable right. It is a myth. A PR stunt to justify a war. It does not, has not and never will exist.
I'm always sort of confounded by this point of view. The reason you think they don't exist is that you don't understand what they are. Yet you (seem to) refuse to consider them, beyond preconceived notions, because you've decided they don't exist.
Inalienable rights are simply an extension of free will - that's it. Saying they are "inalienable" is merely an observation that they are an integral part of consciousness. It doesn't mean that they can't be violated, it doesn't mean that government MUST protect them, or that anyone else must respect them. It doesn't mean they are ordained by 'god' or divine in origin. It just means that the capacity to exercise a right is an inherent by-product of having free will.
The reason it's important as a political concept is the argument we're having right now. It draws a distinction between rights that require the active participation of others, and those that don't. Failing to recognize that distinction leads to the conclusion you have reached - that there are no such thing as fundamental rights and that all of social interaction is competing powers. Further, it implies government with the primary concern of balancing such competing powers. That's corporatism in a nutshell, and it's dangerous.
The cruel irony of these anti-discrimination laws is that they undermine constitutional protection of real minorities, subjecting any and all viewpoints to the approval of the majority. The underlying principle, that our decisions regarding who we do business with should be subject to approval of majority opinion, essentially ensures that any minority can be targeted with such laws.
