> An illusion is just a false perception of reality
False perception to whom?
> Why couldn't I program this computer to think it's conscious
Who is thinking it is conscious?
> and to experience its visual data
Experience how?
All these words you're using already require consciousness.
You're essentially saying "You don't really experience at all, you're experiencing an illusion!" Can't you see how that is a contradiction? The experience of experiencing an illusion can't itself be an illusion. And that's all we're saying consciousness is: that experience. If you experience anything, that's consciousness.
