Is that necessarily true?

E.g., suppose I'm grocery shopping online and get put in behavioral histogram bin #1. You're in bin #2 because of stuff like impulsive browsing habits and low battery. Your bin's price for chips is consequently x% more expensive than mine.

Now, suppose both of us get separate uber rides from the same location. Similar data bins end up with your low battery generating y% higher price for your Uber.

Seems to me enough consolidation and behavioral data-based pricing practically impedes the fungibility of currency. Because while you and I can still borrow and pay back the currency directly to each other with impunity, the literal price of goods and services we can buy with that currency will be different. I.e., if you buy me a sandwich on Monday and I pay you back with a sandwich on Tuesday, you're losing money.

Edit: for the steel man of what I'm saying, imagine most grocery and convenience stores have shifted away from static pricing to something like qr codes. Also, assume pricing based on personal data is rampant across industries for most basic private goods and services.

That may be true, but capitalism has nothing to do wit betting or prediction markets.

You can have those with any government or market style.

Capitalism is just a projection of our natural competition for scarce resources onto an economic system.

The price of everything and the value of nothing.

Betting with one another predates any notion of capitalism, or economy.
