The art market has its ups and downs, just like any other market. Last year it went down. Art buyers are fickle, so it's quite possible that they won't be willing to pay as much for your Van Gogh as you paid. In fact, that's why a lot of expensive art ends up donated to museums.

And of course hype is something found in all markets, not just art. Stories about Gamestop made the news, but the same thing goes on every day for other stocks. Buyers know the game, too. If you spend $100K on a random painting or random stock, it's quite possible others will point and snicker about how you overpaid.

Finally, your article describes how people avoid taxes on art, not how art is used to evade taxes. Unlike other investments, people who buy art generally want their investment shipped to their home where it can be proudly displayed. Shipping incurs lots of extra costs, including import/export tariffs. And people try to various ways to avoid some of those costs.

Whereas someone who buys stocks is happy to let their certificate sit in their broker's office, so they don't have to worry about those costs at all.
