I feel safer knowing someone's got my back. Through networking and studying, I found the screeners I have are legit, professional, and make sure their ladies are treated well... even to the point where consistent douche bags are banished from seeing their ladies. Someone knows where I am and whom I'm with at all times (while I'm working). And they don't take half my income.
I don't have to deal with hagglers, random emails all day, stalkers, or even talking about the awkward things like donations, scheduling, re-scheduling, saying no, charging a cancellation fee, etc. etc. I can just focus on what I strive to do better each day... spend quality time with YOU. (Which I love, by the way...) People tend to take things more seriously when there are repercussions to ditching a date.
I am still independent ... however you want to judge that is on you ... I can choose my own schedule, and I'm freed up for rest time instead of making sure I maintain a relationship. It's really, really nice.
I enjoy the time I spend with a man much more if I have time to rest, groom, and keep myself sane. I feel I can rock someone's world much better when I can hand all that other unnecessary stress off to someone who's ready and willing to do it.

Plus, with my big move, I've been a little air-head lately, hehehe...
