T206CollectorThe difference in your dichotomy is that among the standards in the community, laser cutting is universally abhorred, while erasers and soaking are accepted on different scales. It is easier for you to live in a world of black and white collecting; but many of us are comfortable knowing what is taboo (i.e., trimming) and what is accepted by many (i.e., soaking gunk and erasing pencil marks).
If you are trying to change the accepted community standards in this regard, you will find that you will have very little luck when faced with undetectable alterations -- because there is no way to police your applied moral values.
I believe that the industry standard is essentially driven by alterations that can be consistenty detected. While there may be moral values on both extremes of that equation (puritans vs. laser cutting, color adders), most of us are somewhere in the middle. But I certainly respect your interest in keeping cards pure. If you ever find a way to ensure that better than SGC can, please let me (and them) know.
