I don't get what the added value is of a handbag that costs $2,000. There's good quality materials, high quality assurance, restricted numbers, sales from expensive shops. But still, that's no where near $2,000. So a forger can make a knock off and try to sell it for $1,800; or for $200; or a bad similar bag and sell it for $50. I don't know why they don't make nice bags for $200. This is true when you look at wristwatches. I want a nice movement in a nice case with a nice face for a reasonable price.
There's a lot of philosophy around it if you're interested in that kind of noodling.
"Bob has a science-fiction machine that can make an exact copy of a famous artwork. No one will be able to tell the difference between the two pieces. Bob borrows a famous artwork, but he then gets the copy and original mixed up. Should he tell the museum? Or should he just return one? No-one will eve know, but Bob." etc.
