It's interesting that you are contrasting "things that are beautiful", and then as the main criticism "it's really easy to make".

In the next few years we are going to have this debate over and over again (AI-art). Does art need to be hard to make to be called art? If I create something really beautiful but it only took me a few seconds to make, is it still art? Would your appreciation of an art piece change if you knew the author didn't spend as much time as you thought on it, why? It's still the same piece.

If a future civilization discovers a lost painting, they can't tell how many hours went into it. Art should stand on its own, the difficulty in creating the final piece is a metadata that is biasing our judgement. "Beautiful" and "hard to create" are orthogonal dimensions.
