Our teaching on worthy reception of the Eucharist is the same as yours. However, we leave it up to each person's conscience to decide worthiness. That's not our job. I believe Cardinal Cupich of Chicago takes exactly the same position.  Your premises, even if valid, would present very substantial practical difficulties. Do you want those who distribute communion to interrogate everyone who approaches? Of course not! To do so would be extremely time consuming when communicating a large congregation and, more important, would be an assault on the dignity of the communicant by way of public embarrassment. That said, I am always available to hear confessions by appointment. Finally, the Roman Church teaches that Old Catholic Holy Orders are "valid but irregular." I am quite happy to be "irregular," as "Consistency is the hobgoblin of little minds," whoever said that.
