There's another set of variables that bear on how people decide these things; their attitude toward having a buddy, and toward diving alone. For example, ask yourself what your attitude/taste/preference is toward:
1.) Diving with a buddy. Do you do this because you enjoy it, or because you need a risk mitigator and think this is the best form? People people who enjoy social actives aren't going to think quite like introverts. Some people would mostly buddy dive if there were no risk issue, just as some people seldom go to movie theaters alone, amusement parks alone, etc...
2.) What's your attitude toward diving alone (whether in recommended solo gear with independent gas source, etc...) or just regular gear either alone or your buddy swims off, but conditions are very good? Do you believe such diving is 'too dangerous' or a slippery slope you don't want to get on, or are you comfortable with it? Do you perhaps like it, preferring to dive by your own whim and preference and not bother monitoring a buddy?
Your views on the above are going to impact whether you think the hassles of finding and traveling with good buddies, or trying to get an insta-buddy up to snuff, are a worthwhile investment or 'too much of a PITA.'

Absolutely, I just think this might be falling more in the realm of "I enjoy solo more than I enjoy buddy diving" (or the other way round), as opposed to "I dive solo because the buddy system is defective by design" (or "the buddy system is the only way to dive safely, and solo is defective by design"). I have experienced, on occasion, the thrill of being alone with the ocean, but I never felt that being alone made me safer at all. Rather, I am motivated to improve my skills to a point where I could do this more often with minimal risk. I also take extreme pleasure from diving as a buddy pair with my wife, I often feel more excited about her experiencing something new, than I feel about experiencing it myself. A different kind of pleasure. I never felt that diving as a buddy pair with her made me much safer, though (certainly not to the degree that it would affect the way I dive). Rather, I am keenly aware of the fact that she is dependent on me, far more than she should be. And, this is another reason to seek more training: both in solo diving (you can't help someone when you're dead or incapacitated), and in being a more attentive buddy.
