The point of Banksy’s art is social commentary. More importantly it is location specific. So by removing it from the wall it was painted on means it loses its meaning, significance and value. In a sense Banksy is really criticizing about this kind of phenomenon by choosing graffiti as his medium.
You know, nothing really has meaning.
What I mean by this is that within context things make sense. But what if you expand or contract the context? The meaning changes. So this in itself is an indication of the inherent instability of meaning.
So meaning is contextual. It is empty of any independent “substance”. Nothing new about this. Socrates said something similar about words in Cratylus. As did Buddha. And so the jump to this conclusion is not hard to reach.
