Trying a different question

Syp made a post about the validity of solo play, despite him being mostly a grouper. Due to the back and forth in the comments Ysharros had a stab at defending their playstyle of preference. I threw a comment out there myself. Spinks on the other hand has a different view and once again the comments flow, as doother posts.

Here's something I want to ask though.
Grouping is fine for those who group. Reasons have been given ranging from personal achievement, enjoying a metagame, tactical reasons and so on.
Soloing is fine for those who want to. There should be an overlap permitted but both camps seem to have a problem with that.

My question is this. Soloers, what would entice you to group? You have your reasons for not doing so, and that is acceptable. Maybe you don't always feel like it, maybe you dislike the chaos, maybe you have a medical reasons (I've known a few).

When the solo vs group question comes up, inevitably the question posed is "Why would you solo in an MMO?" with the implication to some that soloing is the digital equivalent of leprosy.
How can we make the question "What would get you to group with us?". People don't have to group, people will always still want some alone time, me time, time to do whatever insanity or drudgery catches their fancy. Could you make it enticing to group though, even to a soloer, without necessarily forcing the issue?
