except predication of choice makes it literally not inherent

Things aren’t any less meaningful just because you chose them. For example I’ve been playing the same guitar for over 20 years. That instrument is now inherently meaningful to me in a way that others are not. It’s inherently irreplaceable to me. You’ll find most musicians bond with their instrument in a similar way

neither does potential imply inherent either

Of course it does. Every time a guitar is destroyed on stage thousands of discussions break out about how upsetting and wasteful it is. How it could have been so meaningful to a child who wants to play but doesn’t have the means.

We see these things and we want to connect them with the people who their meaning will most benefit, precisely because they are inherently meaningful.

big list of horrible things

The question of whether or not you will experience extreme suffering is not relevant to the meaning your life possesses. The 5,000 people who were just swept away in Nepal have not had their lives rendered meaningless, regardless of whether or not they would have chosen not to be born if they knew that would be their fate
