and you're still returning to the "nature's plan" nonsense. I guess if nature says you should be near-sighted, you shouldn't correct your vision with glasses. That's blatant interference-who are to interrupt nature's plan for you that involves you bumping into furniture and being unable to drive or read street signs from a distance?
Actually, I'm pointing out the progression of philosophies debated and adopted by characters in-universe. If "nature's plan" is nonsense to you, take it up with Troi, Phlox, et al. They were the ones taking the idea seriously. What I'm saying is that in-universe there is clear progression over the centuries, in how the characters interpret the proper role of themselves within the context of a hypothetical "nature's plan". That should be clear from these and other episodes.
