Let's see if I can capture the two positions.

You (and others) appear to believe that unreliable messaging is a
problem requiring a solution.

My belief is that the problem is "reliable coordination".  That is,
how do two pieces of software distributed on an unreliable network,
coordinate to achieve some goal in a reliable manner (such that both
know that the goal has been achieved or failed, etc..)?  So I see
"reliable messaging" as just one possible solution to that problem.

Does that help?
