You have a misunderstanding of what a circular economy means,

Circular ≠ boomerang

Circular = sats flowing from p2p wallet to p2p wallet

Circular = Value 4 Value

Circular ≠ random zaps, randomly come back to me

That's nonsense.

For ex,

I sold comfrey to plebs for zaps,

You can publicly see the zaps on my profile,

I am now looking to spend those sats on other goods and services on Nostr,
