But, it's your life. Just do us all a favor and don't get a boat-load of friends and/or kids hurt or killed when you find out how valuable it would have been to have developed your sailing skills on a smaller boat.
I don't doubt dinghy sailing experience would be advantageous, I just don't think it would be the only way to learn. I would think it would be more dangerous to take out a "flippy little boat" on the SF Bay, especially in bad weather, than a sturdy keel boat. Maybe it would've been different on a lake.
Not sure why this point of view irritated you, but if it makes you feel better, I did state that I plan to single-hand most of the time. I also intend to take plenty of lessons and stay in protected waters until I'm confident in my sailing abilities, as well as take every safety precaution possible. If that seems reckless to you, well, we'll just have to agree to disagree.
