Very good point. People who favour this reasoning tend to miss the point and do not see the hours put in to the craft of the genius.
There is no escaping that no matter what there will always be work required to attain some skill.
Personally I learnt this the hard way. Whenever I now start to do something I try to fail as quick as possible as to see where I went wrong and build on it.
I hate work. But I love self improvement.
