I'm not sure if that's what Humble Marksman was getting at, but your description is good to go for me. It highlights the variations of "sight packages" required based on target size, distance, shooter skill, etc. and of course all the other stakes - especially off the range - which come into play.
I may not completely agree with the OP and title of that video because it could lead some to an incorrect conclusion the use of sights is not regularly required for the effective use of a firearm. Your response just saved me a time-expensive deep-dive on the subject.
Thanks, CF.
