> saying "it's because charge comes from spin" is the sort of obfuscatory answer

If you refuse to ask further questions, yes. If you keep asking why, it opens the door to what charge fundamentally is.

> All charged particles have spin, but not all particles with the same spin and other similar properties are charged

Spin and charge are fundamentally connected. That said, I was answering according to SOC, which remains a hypothesis.
