Don't confuse preference with reality.

My preference is to camp alone. The reality, when you've only got a day or two to spend, and have to hike in the Ohio River valley, is that you'll probably end up camping near at least one other person or group. In such cases, you can maximize separation, but in areas where camping is only permitted in designated backcountry sites, "maximize" and "minimize" are sometimes synonymous. But it's still better than not going at all.

Also, there may be some interpretative differences as to what "camping alone" means. To me, it means not only solo camping, but camping with only one or two trusted and compatible hiking partners, as opposed to going out (as I did this weekend) with a more-or-less organized group of folks, most of whom I didn't know. It was enjoyable hiking with them, but when we camped, I set up my tent a couple hundred yards away from everyone else, and still turned in when it got dark, leaving them to their social gathering around their campfire. I don't consider that camping alone, of course, but it was an adequate compromise.
