I'm missing the links in your post (click here), except one.

There are many reasons why we use the tuning that we have now. And I don't believe music will sound the same when one plays it based on the 432 Hz reference point versus the 440 Hz reference point.

If that 432 Hz frequency is that natural -- I don't have neither knowledge nor means to prove it -- I suspect my guitar should sound different when recorded while played tuned to the 432 Hz based scale compared to a recording that was played tuned to the 440 Hz based scale and then the recording would be electronically tuned to the 432 Hz based scale.
