I prefer not living alone, and of course since I'm married, the two of us is a perfect household. I get uneasy if we have any overnight company for more than a couple days, as it disrupts my daily activities. But on the other hand, I don't want to get to be an old hermit, or force my wife to not have friends. I have lived alone from time to time, and I find that I miss having someone to talk with, etc.
As far as practicality, I have no problem keeping house & home alone, but it's lonely when my wife is gone for a few days to go camping with her horse riding friends, etc. If anything, I'd think that Aspies might do better than some NTs living alone, as we tend to do things in a very routine and orderly manner. At least speaking for myself, I prefer do to all my own laundry and housekeeping, and in fact my wife wants to hire a maid, and I don't want a maid. She thinks it's not fair for me to do much of the housekeeping, because she doesn't like it herself (although she can do a great job). I like to do it, and I don't think a maid would do as good a job, when it's not her own home, and I don't like my stuff messed with. Nobody has touched my laundry since I was about 7, and I'm very meticulous about it.
I probably rambled off-topic, but the bottom line in my opinion, is that an Aspie can live alone or with a household, as well as anyone else should be able to.
