Dives 1-8 were for my OW class and I am glad I did a longer course as 4 dives would not have been enough for me to be comfortable in the water unsupervised, but 8 dives was enough

Dives 9-14 were club dives with a DM for two reasons - to get to know the local sites and also because I didn't have a buddy to dive with then.
Have not dived with a DM since as I have a buddy and I have books and websites to look up information on sites. Also DMs are not common locally, only really on club run dives.
It is interesting some of the words people here use to describe diving with a DM - "handholding" "umbilical" and so on. The DM lead dives I went on were guided only so it is not always about needing supervision... I was assigned a buddy on the DM lead dives I did and the DM basically swum ahead and pointed stuff out, that was all. They did not do anything other than this, i.e. no gear setups, no watching my gas supply, and so on.
NudeDiver:
After you got your first (unrestricted) driver's license, how long was it before you made your drive without adult supervision? If you're like, what I have to believe is 99% of the public, the answer is, "not very damned long!"
I can see the point you are making NudeDiver but firstly, often people do not leave OW courses comfortable in the water and may need a few guided dives afterwards. This is not their fault, more the fault of their instructor but what's done is done so if people need DMs for a bit afterwards, I can understand why.
Also your analogy with driving licenses is flawed in my opinion. Most people do not learn to drive in four days for one thing. I got my Learner's permit at 16 and had hundreds of hours of supervised driving experience in the two years before I could go for my license. Then I had three years on a Probationary license, where the rules are stricter than those who have full licenses (and even more so these days for new P plate drivers - can't have more than one passenger of the age 16-21, not allowed to use a hands free mobile, can't tow anything, etc so one is not allowed free reign even after they have their license).
I'd say 99% of people who had hundreds of hours of supervised diving experience would be happy to go out alone after certification
