It seems the opposite: toil makes us human. Our inability to accept what can be foraged has pushed us into working.
I always took this to mean precisely what you said. "From the sweat of your brow," you eat because you chose to define for yourself "good and evil" with respect to nature's provisions.
I like to connect it with Douglas Adams' answer to the meaning of life from Hitchhiker's Guide: 42. The number itself is shaped like a human bent on their knees toiling in a field.
It's more that foraging limits population size, and when people have to compete for resources they end up killing or starving each other. Humans have a drive to grow and reproduce, and they have been more successful by working together, then by industrializing (e.g. agriculture). Because they got so good at it, one person could do the work to feed nine others, meaning the other nine didn't need to work in food production anymore and could do other things.
(oversimplified, you know what I mean)
Everything's been abstracted away to things-exchanged-for-money though, nobody needs to forage or build their own homes anymore, just fork over cash and it's there. Getting said cash, there's myriad ways to do so and we keep inventing new ones, like... recording oneself queueing up at Disney World, or dressing up in a maid outfit and doing NPC emotes for money.
