Devil's advocate for why ontology is meaningless and vacuous.

Me again. I missed out a stage, which you'd already mentioned. So let's start again:

Type 1 realities: Inflexibly shared realities, such as "our objective reality". The realities can be altered, obviously, but the alterations then apply to anyone trying to access the reality.

Type 2 realities: Direct experiences, such as the phenomenological representation of a type 1 reality. In a lot of ways, science is all about comparing the overlap of our type 2 realities to try and learn, indirectly, about a type 1 reality.

Type 3 realities: Indirect experiences, such as our imagination or dreams. These don't have to come from any other reality, and don't have to obey any particular rules as such.

Type 4 realities: Flexibly shared realities, such as fictional worlds or abstract ideas. We can pool ideas to create realities to later draw on. But we can also alter them however we like individually, as we see fit.
