I suspect they might be. I'm not sure their mind will change especially if there are alternatives, but its always worth having these conversations IMO. 

Blocksize increases are a hammer and a lot of these problems don't end up being nails in the end - but some problems might indeed be nails.

I was totally closed off from any blocksize increase at all but changed my mind when I saw it from a lightning perspective. I wonder if other never-forkers would be susceptible to the same framing.

Hear me out: How can we start talking about a blocksize increase?

I find this to be a coherent argument. I don't think many technical Bitcoiners would be allergic to such a discussion. I'd categorize this as less a problem with blocksize and more a problem of governance generally. Hard forking the network is just a problem in and of itself and they'll probably only happen when the network is desperate. Hypothetical need/want isn't enough even for a soft fork.

I think the best thing you can do if you're concerned about the issue is follow Rusty's lead and promote the discussion more, so that if this problem appears people are a little more open to hard forking.
