Do you have any basis for this statement?
But if consciousness is only a property that doesn't influence the actual physics, then how are we even able to talk about consciousness? Why would it occur to physical beings that something like consciousness exists?
We conscious beings can talk about consciousness because we can never understand how consciousness arises from the actual physics, and can't talk about that. By not being able to comprehend how physics and conscious minds interact, our minds can talk about each separately. Perhaps the same principle extends to various components of physics, such as General Relativity and Quantum Mechanics -- maybe our consciousnesses are incapable of conceiving of the math that unites them. After all, Mathematics is simply only a product of our conscious minds.
What do you mean by "dualism"? Substance dualism, property dualism, predicate dualism, hylemorphic dualism, etc?
Also, you speak as if dualism and some form of materialism or physicalism (there are many) are the only options available to us. What about idealism? Or neutral monism?
Consciousness is an incredible thing. Reducing it to a mere property is akin to pretending it doesn’t exist at all.
What about people born with out sight or hearing or both. Do those individuals not have a conscious?
Consciousness is not a 'thing', it is a property. Thus far we know of only one sort of system that can hold the property (human beings in our environment) although we do gain some information from observing humans of different configurations (such as seeing that people with total facial paralysis experience significant emotional dulling and substantial changes to their subjective personal experience over time) that hints at what things are important for different aspects. So far as we have evidence for, there is no reason to think that you might be able to, for instance, simulate solely a brain and have anything akin to consciousness. Just removing patterned sensory input from a typical person via sensory deprivation quickly results in their consciousness dissolving. So how a brain without a body and without an environment to perceive might ever have a hope of consciousness I've no idea.
