One more thought. This is a video of Andes Segovia who is considered the father of current classical guitar. He was born in 1893 and in1928 Segovia made his American debut in New York City. This is video of him. https://www.youtube.com/watch?v=2eBnfzngq9Y
What is interesting is he had short stubby large fingers and most of the early players did not have long finger nails. It was unheard of then and the long nails are more of recent trend. You do not need long nails to finger pick. I do concerts and have never had long nails. Today many of those you see with long nails cut some of them from ping pong balls and glue them to their nails and coat them with layers of hardener. They then shape their nails to look more normal. When you look at them they look long yet they look white in color.
My point is any one can learn to play either classical guitar or steel sting guitar without long nails. And as Andes Segovia proved long ago, you can play great with short stubby fingers without long nails. There are no rules on who can learn to finger pick and who can not. You just need to spend the time to practice and learn to play the music you like.
Music is what feelings sound like.
Music is life, that why our hearts have beats.
