Yes, because when it comes to most artist expression the process behind it is the product. These pastries have cultural weight, so their value is inseperable from that.

Think of it this way. Nobody would eat a Karelian pastry and not care that it's Karelian. That's why they're eating it, otherwise they'd just eat some other pastry without the cultural weight.

It's the same thing with paintings and sculptures. The painting has value because someone thought it up and put the time to make it. And you view it not for the colors, but what they mean. Why did they choose to paint this? What was going through their heads? What is their perspective?

If you just shoot out a painting, it has no value, because the value isn't the painting. It's your take, your perspective, and the painting is a tiny window into that.
