I understand your points, but it remains a fact that FL is a mod within the game and FL is difficult. The ability to memorize a map and FC it with FL (with decent accuracy) is just as much skill as any other osu skill (reading, accuracy, consistency, stamina, etc.). Since it is in the game, and it is difficult, it should be rewarded. If you think it shouldn't be in the game you should consult peppy, rather than not rewarding players for their skill and effort. Keep in mind - pp is short for performance points. This means that your rank is based on your performances and not your skill.
Let's take a hypothetical situation where a lower ranked player (30-50K), by pure luck, SSes Freedom Dive. Now, obviously this is not possible, but let's say that there is a 1 in 100 quadrillion chance that somebody SSes Four Dimensions by pure luck, rather than skill. They would still receive the same pp that a skilled player would for that play, because they're judged by their performance and NOT by their skill. So, regardless of how often you need to practice a map, if you achieve a score that others can't achieve easily, you should be rewarded for that performance, just like with any other mod.
Discouraging repeated practice on the same map is like discouraging osu. rrtyui played Big Black around 3000 times before SS-ing it. Does that make his SS any less impressive? And does the fact that he played it that often (because it's a difficult map) mean that his score shouldn't be rewarded?
The answer is no
