people would have lots more free time, instead of looking for ways to fulfill themselves sexually.

As an asexual, I can tell you that unfortunately that’s not the case. I suck at life, procrastrinate most of the free time I have and I’ve never really felt like it’s any kind of an advantage that I don’t have to deal with it, as far as “being more accomplished” is considered.

But I agree on your other points. I have amazing relationships with other people of both genders, because it turns out that it’s really a lot easier to make friends when you don’t need to fight the urge to bone them, or have an ulterior motives.
