Same with paintings, etc. So yeah it's a wonky argument because it ignores subjective judgement
Most paintings don't have (much) value. Behold my latest work, the brown ring of quality... do I hear... 5 cents?
A few paintings have value, primarily due to the fame of the artist or the history of the piece (It hung <place>). Supply is frequently capped by the fact the artist is dead...
It's much more impressive to those people to have paid to support the original rather than having a knockoff... This has been true as long as goods have been produced.
This is a funny way of saying "to enter a speculative market with foolish money."
