I don't understand what is interesting about it: it's the default.

Markets don't run on altruism.

And humans don't run on markets.

Mostly they kind of do since we do live in an utopian society of unlimited abundance. Extremely few people can afford to (or want to) spend a very large number of working hours without ever getting anything directly in return for it.

I think you made a typo of saying do instead of don't and totally reversed your argument

Neither on altruism.

The standard is applied very inconsistently. Nobody accuses the local bakery of being motivated by profit, and that they don't bake bread for you out of altruism.
