I don't see why people struggle with consciousness. I've found it to be concrete. It's the experience of having inputs (vision/hearing/etc) and outputs (response to stimuli). Whether or not you're actively aware of "hey, I have inputs and outputs" doesn't really matter. It's just the process of it.
Do you have a pet dog or cat? It's obviously conscious. I guess my construct breaks down if we consider things like plants, they obviously respond to their environment.
