Admittedly I haven't done a close read, but on first skimming I didn't see anything that limits this to commercial transactions between arms-length buyers and sellers. Where are you getting that from?
To my view, there's a world of difference between "You can't use PayPal as a payment processor for gun sales" and "You can't use PayPal to pay pals back for covering your range fees last Saturday."
Yet the AUP seems broad enough to cover both: "You may not use the PayPal service for activities that... relate to transactions involving... ammunition, firearms, or certain firearm parts or accessories...." https://www.paypal.com/us/legalhub/acceptableuse-full

Firearms are for absolutely no reason what-so-ever taboo on most payment processors. The AUP is broad enough to cover both because the pearl clutchers don't see a difference. The best part of this is "certain firearm parts or accessories" as if they had a qualified expert anywhere in their company that could identify a bolt from a slide. It's deliberately written to trap you, and now, extort you for $2,500.
I think it's simpler than that. Some executive didn't want to have to hire a PR crisis management firm if some kid shot up his school with a gun bought through their payment system. Same with a lot of other stuff. It's all about money.
