This is an extreme statement, nothing personal. Many experienced divers would not agree with that statement who have been doing this (solo) a long time. This redundancy thing is getting out of control and is a result of everybody playing tech diver and extrapolating from non-experience and on unlikely scenarios.
That said, 17 dives seems a bit premature but then I must admit, stupid or not, I did my first solo dives when I was in my early teens on the sly and never looked back so stupid or not I am still here and usually did and still do dive without any redundancy but for the surface above.

Right on...
I often see posts about needing doubles and redundancy for recreational diving. The amount of risk being undertaken on depends on the diver's experience and abilities. For some, it may be dangerous to do a solo dive on a single tank, while for others it may just be walk in the park. It depends on the diver.
As a PADI DM, the company response is that solo diving isn't safe and no one is ever ready to solo dive. If that's the kind of life you want to live, go for it. However, life never fits neatly in a box. I started out doing light commercial dive work after taking only a short NAUI recreational class. Within 10 dives of certification, I was diving solo to 130 with minimal equipment, and then began doing deco with no training at all. I was told how much deco to do by topside support and I followed instructions.
There's a saying in commercial diving: Anyone can dive, the difficulty is finding someone that can work once they get in the water. The thinking is that it's better to take someone with skills and teach them to dive than it is to take a diver and teach them skills. The message is that anyone is capable of diving, but most are useless once in the water.
It's an individual thing. One diver may be ready after a few dives while another may not be ready after hundreds. The sum of an individual cannot be defined in PADI terms: OW, AOW, Rescue, etc.
If you don't push your limits, you will never know what your limits are. If you never challenge yourself, you won't be able to rise to the challenge when necessary.
