I have nothing against sharing per se. My issue is with the family nomenclature. In your case it might align perfectly, but for myself and most people I know, it's not the case. That is, the set of people to share a Netflix subscription with, share Steam library with, share Kindle library with, share passwords to various web services, including utility companies, are only partially overlapping, and do not align perfectly with the idea of "family" or "household".
