Emotionally, it feels different. It's fascinating to see downright angry gut reactions!
A few years ago my friend was selling his expensive camera on Kijiji. I asked him to sell it to me for slightly less as a friendly discount. He told me that's the same as just randomly one day giving me a wad of cash, so why would he do that?? I thought he's crazy and was a little bit offended. Actually maybe a fair bit offended!
It took me YEARS to realize that 1. He's absolutely completely Inarguably correct, and 2. People would find me no less crazy if I adopted same perspective.
Buy for $x, have and not sell for $x, same mathematically. But oh boy will people get instantly riled up emotionally :).
But I would never sell something expensive to a friend, period. There be dragons.
Price and value are not the same. The logic of your friend was basically putting a price on how "special" (or not) he saw your relationship versus some rando-buyer online.
That is why people (close to you) get riled up emotionally: they're being treated in a way no different than a complete stranger.
Sort of. People are being less irrational than it sounds if you account for transaction costs. There's a lot of stuff I might "sell" if I could point a video-game-like pointer at it and right click and hit "sell", and it just instantly disappeared and money was credited to my bank account. Perhaps even more if buying was just as easy and I didn't need to hang on to something like my drill which I don't use very often and I could trivially "rent" it from the market by buying, using it, and selling in mere minutes.
But in practice one-off selling for anything less than $100 or so is a waste of time because there are significant transaction costs for one-off events like that.
>Buy for $x, have and not sell for $x, same mathematically.
They're not the same.
£20 item to buy, I have £100; buying leaves me £80. Either, I have £100; not buying/selling leaves me £100 £20 item I own, I have £100; selling leaves me £120.
In the first case maybe I can't make rent now. In the last case I have more cash, but then I need to spend money if I want entertainment/utility that the item had. In the first case I lose 25% of my cash; in the last I gain 20% (this matters when you're sharing your money across different needs).
