The question regarding something from nothing I interpret more as the fact that we have to start with something for the universe to exist. In my essay I use the something from nothing as a way of explaining the model. My assumption is that energy and space must exist. If the universe was nothing we would not be here discussing it.
Regarding information and interactions I agree that a single charged particle will have no electrical force on it, since a force would require a second electrical charge, however it can still have a charge on it. Information about the charge of the particle can only be known if an exchange or interaction with another charged particle occurs. Hence information is about changes in states.
Regarding your comment on space quantisation, I do not understand why this has to be from an imaginary observer outside the universe. If quantisation of space is how the universe is, then that is how it is from an observer inside the universe as well as from the outside of the universe.
