Dear Alex,
You can certainly have such a class, but I don't think it is necessary. The
critical thing is the identity criteria that enables you two say two things are
in fact one.
I don't think a grain of sand needs an observer to have identity. However,
capturing data about the world will require an observer of some sort. I would
consider some objects as "natural" that is they are reasonably well defined
whether or not we exist. Cats dogs and grains of sand would be amongst them.
However, there are also certainly plenty of intentionally constructed objects,
like money and contracts and organizations that could not exist without our
determination of their existence, and are what they are because we say so. (01)

An identity - as a specific classification of a thing in a such way that the
correspondent class has one and only one member? (05)
And I think that an identity seriously depends on a viewpoint and an observer
who/which makes that identity ‘classification’. (06)

Alex
