Can Economics Be Discussed Without Psychology?

...so I was thinking that maybe macroeconomics shouldn't exist at all because of its intrinsically top-down perspective on how economies exist. They basically operate on the premise of spontaneous generation. If you set up the structure, agency will just magically appear because of how people compete for attention...

...but isn't that the problem? Why would anyone design an anti-social economy where people are expected to compete for attention? The very premise of focusing on structure before agency suggests that people can't control themselves, and that people should be entitled (possibly expected) to behave like animals.

Coincidentally, Keynes believed in exactly this:

A lot of human behavior is instinctive. People really do not consciously control much of what they do.

I think there is some truth to that. I mean if I had to consciencely think about everything I did I wouldn't get much done in a day. I need to be able to think about task A while performing task B with little or no conscience effort. Ironically enough, you can call that "multitasking!"
