When in use, sure.

Citation needed. Actually, since the 3.5mm port is deeper, and the 3.5mm jack thicker, physics says the same amount of force would be better spread out via 3.5 connections than via a shorter, thinner connection as Lightning.

When not in use, why not just keep it attached to the headphones?

Uhh, personal experience? I've certainly bent my share of 3.5mm plugs, but I've yet to hear of anyone actually bending their lightning cable plug.

This is a specious argument. Physics does not say this at all, because you haven't defined the materials you're working with. If the lightning connector and the 3.5mm plug are made out of the same material, and the 3.5mm plug is completely solid, then you could make this argument. But in my experience 3.5mm plugs are not made out of material that's as durable as the material lightning cable plugs are made from, and 3.5mm plugs also often give the impression of being hollow inside. Sure, you can probably make an extremely durable plug, and I'd guess that more expensive headphones probably have more durable plugs than cheaper headphones, but regardless I don't think you really have to worry about bending your lightning connectors.

And in personal experience, I have never once damaged a 3.5mm plug, despite extreme rough use (and I mean the "extreme"). Can't say I have bent / never bent a lightning plug though, since I've never used an iPhone.
I wasn't worried; I was making the argument that the lightning connector is more durable (in my experience) than 3.5mm, hence anyone who's satisfied with the durability of a 3.5mm plug (as you seem to be) would have no problems with the durability of the lightning plug. If you're not worried about this, why did you try and argue against it?
By that logic, I'm not worried either. I just don't agree with your belief that the lightning plug is more durable than 3.5mm. My disagreement with your belief was the argument I was making.
When in use, sure.
