I lack ambition in other ways, too. For example, I don't have a job, and I shudder in horror at the thought of having one. As far as I can tell, women usually don't want a long-term romantic partner that is neither a breadwinner nor a competent homemaker. And by "escape the world", I mostly mean "escape from the experience of living in the world," through such means as playing World of Warcraft (which, incidentally, I tired of after a few months) or the final, irrevocable escape, death.
Some people - including some women, for example myself - consider that a reasonable preference, too. Personally, I find it much more disturbing that you seem to be focused on standard definitions of acceptability. Actually, if it wasn't for that, and the ways I suspect it affects you (I'm making assumptions there based on when I was in a similar phase in my life, so could be wrong), I think you and I would get along more than passably well. (Possibly relevant context: I'm moderately-to-strongly asexual and not actively looking for new strong relationships at the moment.)

2:45:35 PM Katja Grace: Or do anything much
2:48:03 PM Michael Blume: *nods*
2:48:07 PM Michael Blume: this is indeed a problem
2:57:55 PM Katja Grace: Maybe there is a dating site for smart ambitious nerds somewhere
2:58:25 PM Katja Grace: Need to set up lw extension perhaps
2:59:02 PM Michael Blume: haha, yes ^^
3:00:40 PM Katja Grace: Plenty of discussion on why few girls, how to get girls, nobody ever says 'oy, girls on lw, want to get together some time?'
3:01:14 PM Michael Blume: somebody really should say that
3:01:34 PM Michael Blume: hell, I'm tempted to just copy that IM into a top-level post and click 'submit'
3:01:48 PM Katja Grace: Haha dare you to
