23 Conspiracy Theories That Are Actually Pretty Convincing
I believe that modern/minimalistic art exists solely for money laundering. It's just a way for rich people to move money around.
Art is fake
I don’t necessarily “believe” this, but I’ve always speculated that a lot of priceless artwork and historical documents are actually replicas or copies.
Obviously a painting by a world-famous artist using a very specific technique would be very hard to fake, and I don’t think that every art scholar in the world is paid off in some grand conspiracy. Rather, I just think that either the national treasures never left their vaults or that some national treasures actually were lost to history but they were copied.
