As for replying more directly to the arguments you linked: my views combine a bit of Khorton, a bit of both Aidanresponses...
...and also, a lot of credence in most of those arguments. That’s why I work a meta job, spend some of my free time on meta projects, and advise people toward meta giving when I can—including the foundation I work with, which recently made its first meta grant after decades of exclusively near-term giving.
(By the way, this was a good question! I didn’t even hint at this stuff in my original answer, and I’m glad for the chance to clarify my beliefs.)
