I was under the impression that interaction has to do with information
transfer and that that takes care of the fact that there cannot be an
information transfer without physicalness. At least according to this
source:
"Distinct memory states label and 'inhabit' different branches of Everett's
'Many Worlds' Universe. In this manner, the distinction between epistemology
and ontology is washed away: There can be no information without physical
representation. Persistence of correlations is all that is needed to recover
'familiar reality'."
