That's like saying it's unnatural for every interaction to take place over a computer, when no one is saying every interaction should take place via a computer. Money is a technology for scaling interactions between people who don't know each other, and prices efficiently communicate changing economic conditions.

No one is saying you shouldn't lend your neighbor a tool or a cooking ingredient if you want to do that. But people who want all economic transactions to be part of a "gift economy" where money doesn't exist, or some other such nonsense, are generally either idiots or parasites, often both.
