God is not holding anyone guilty for the sin of another, not even the sin of Adam

That is not what Romans states:

Rom 5:16-17 And the free gift shall not be as by one having sinned; (for indeed the judgment was of one to condemnation, but the free gift is of many offenses to justification. For if by one man's offense death reigned by one, much more they who receive abundance of grace and the gift of righteousness shall reign in life by One, Jesus Christ.)

The comparison between Adam and Christ cannot be overlooked. Otherwise you would have to say that not everyone in Christ is made righteous. Death comes into the world through "...one man's offense...". Death can only come to those who sinned. Likewise, much more do they receive abundance of grace through Christ. It is simple logic.

I can think of no greater explanation of original sin than Romans 5.

Death comes into the world through "...one man's offense...". Death can only come to those who sinned.

Again, Paul said 4 things explicitly in that earlier passage: 1. Sin entered the world through one man. 2. Death came through sin. 3. All men die because 4. All men have sinned.

He did not say that Adam's descendants died because they were held to be guilty of Adam's sin. He did not say that Adam's descendants sinned because Adam sinned. He did not say that Adam's descendants sinned because Adam died, though interestingly he does say that sin was in the world and death through sin even though God was not holding anyone accountable for it in the absence of the law. Elsewhere (Romans 8:20) we see that the entire creation was subjected to the bondage of decay and death by God in response to Adam's sin. So everyone, including the creation itself, in between the time that Adam sinned by breaking a direct command and the giving of the law, was experiencing the bondage of decay and death because of God's response to Adam's sin, even though God was holding no one accountable for sin in the absence of the law.
