We know personality doesn't matter in attracting females, or if it does, it's not a good sociable personality that is rewarded the most but instead dark triad, anti-social personality paired with good looks. Aside form that, as a result of no gf, incels often have to cope with very obscure and varied topics, that would by itself seem "interesting" to the average normie.
But for incels that ascend, they no longer have to cope this way. They've been integrated into the world and can be generic and mainstream as they want and not get bored. In the process, ascended incels often lose a lot of their interesting personality.
So do you think you'd lose some of your "interesting" personality and become more boring and NPC-like in behavior over time if you had a gf? Notice this is not to say that it's better not to ascend if it means no longer having an interesting personality. It's obviously better to ascend and become a boring normie than rot alone without a gf and have interesting, obscure copes.
