Isn’t most art for money laundering.

Certainly not. Millions of people create art every day for various reasons and various success. Heck, artists are generally known to be on the poorer end of society. That is the case even for some of the now most famous artists in history.

Is some art in certain circles used for money laundering? Most likely, but that’s definitely not “most” but at best mabye a few thousand pieces which are dwarfed by the billions of art pieces around today.
