I understand your POV, but I will disagree, you make it sound like taking a pony tank is a bad decision. Just because you have a pony doesn't mean you're in a solo dive mindset. If a buddy has an issue I will hand my pony over and stay with them, or donate my primary to them and take my alternative reg.
You talk about trusting your buddy, and I think trust doesn't have to go both ways. I can dive with a new diver, and not trust him, but he can trust me to be there for him. The pony is just there for a catastrophic failure of my primary air source. You don't need to have a solo diver mindset just because there's a redundant air source available to you.
Here in South Florida we're drift diving, and the visibility isn't always great, like the past few weeks have been maybe 5 feet? Not conditions I want to rely on a stranger in.
I also understand this viewpoint but if you don't know your buddy and don't trust them then they probably don't trust you. In 5 feet vis and high possibility of separation you are effectively diving solo. If only one diver has a pony s/he is OK but the person without is not. For this reason I would never buddy up with anyone with a pony. That diver doesn't need me and doesn't need to stick next to me. Of course, you will protest that you are not like that - I am sure you are not, but I don't know you so don't trust you so will not dive with you. The solution is for me to have a pony. No problem. Now I don't need a buddy thanks.
