Both are fair points. Still, a table - or chair - is/was one of thousands of options to choose. So you might be right that good examples tend to be reproduced. Question remains why it would be a good example to begin with.

Personally I think at some point such choice became baked in into the concept of physical existence because people think in pictures and physical existence in itself is such an abstract thing. The choice of furniture however is kind of hilarious.
