If you find a person whose preferences aren't transitive, you can make infinite money.

Let's look at three preferences and call them A, B and C. For simplicity we define 'The person likes A more than B' as A > B. And we say that those three preferences are the ones that are not transitive. We can define them in such a way that this holds:

A > B and B > C and C > A

Furthermore, without loss of generality, we can assume that A, B and C have all the same monetary worth.
First we acquire A, B and C ourself. Next we gift that person the object A. The next step is to offer the person the object C and exchange it for A plus a small fee, which the other person accepts because they like C more than A. So now that they have C, we repeat the step but now offer B which they like more than C, and we can continue that and they'll accept because the preferences aren't transitive.

You expect to make money from gifts? What if they don't accept a gift they don't want? There goes your fee, lol

@faery Who wouldn’t want a free gift?

faery · F

@Luke73 I thought the object was to make "infinite money"?

Luke73 · 26-30, M

@faery So you wouldn’t accept a free car? And you wouldn’t exchange that car for one that just one dollar more?

faery · F

@Luke73 Sure, but that won't make you infinite money.

Luke73 · 26-30, M

@faery It would, the cars would have all the same value. And each exchange I'd get one dollar. And you'd exchange infinitely because I'd always have the care you like more.

@Luke73 So some unknown individual/s buys cars for people that they don't like, then the recipients exchange those cars and you collect the fee, not the dealership? Because currently, the dealership does collect those fees and they are often called a 'restocking fee'.

Luke73 · 26-30, M

@faery The cars are just an example. It would work with any other thing too, as long as the criteria is met or rather not met in this case.

@Luke73 Theoretically, I guess. I'm just not sure what actual service you provide or why any business would allow a third party to collect fees for services they provide

Luke73 · 26-30, M

@faery Why would there be a third party involved? I've never mentioned a third party.

faery · F

@Luke73 You are the third party in your scenario. There is the seller/purveyor of said goods, the recipient of the those goods and then there's you collecting the restocking fee. Or are you saying that you plan to be the purveyor of the goods?
