Can You Make Matter Out of Pure Electrons?

If you swapped all the electrons in the universe, nothing would change. But don't some of them have like spin in different directions and can't those directions also be infinite? Well, the spin can't be infinite because that's quantized, right? And so they can spin up one half or down one half. There's only two possibilities there. Though there are an infinite number of spin axes for these electrons. My point is just that that's all there is to the electron is this list of characteristics. Nothing else is no like identity to each electron. Can you build a complex thing out of just electrons? Yes, exactly. What are the emergent properties of a blob of just
