> Many would argue that the Mona Lisa required an immense amount of skill and technique, and is a very high quality piece of art. Modern art (squares and circles) that anyone can make, I just don't see why it has the same value.

No art critic or collector makes that argument, and it's an uniformed position to take. People don't pay for the skill - there is no shortage of (very poorly paid) people who can do a convincing forgery of a daVinci.

Something to consider.
