You make quite a few assumptions in this post.  The Sacrament of Confession is hardly the only avenue that requires a sincere attempt to change one's sinful ways.  As anyone in a 12 step program, or in prison rehabilitation, or therapy, or just talking to a spouse or good friend would know.  As to Eucharistic entitlement, I don't know too many Catholics who feel entitled to it, as much as they feel the Church is going overboard forcing people to jump through hoops and turning the Eucharist into some sort of Catholic trophy.
