It's a bit like school,
When an individual or small group of kids does something really stupid, perhaps beyond the scope of common sense, and suddenly such activity is banned. The kids who behave responsibly are suddenly cast in the same mould as the "bad" kids, in a method used to protect the stupid from themselves.
A government, elected or otherwise, has a duty to protect it's citizens collectively. While they can go about it in a cack handed way, such as in this case, I undesrtand what they are trying to achieve.
It would appear that most of the posters here are riding gods, never had any training and could ride a 1000cc sportsbike before they could walk. Good for you.
There are others out there who are not so similarly gifted, even though they may think that they are. There are plenty of bikers out there who, because they drive a Ferrari, think that they can handle a powerful sportsbike. Some can, some simply can't.
So, what is the solution? The government either takes a "weakest link" approach and legislates for the lowest common denominator, or introduces a complex graded licence and number plate scheme that can identify, at a glance, that the rider falls into various licence catagories, from Darwin Award, Numpty, Don't Let it Breed, Harley Rider, Weirdy Beardy, Average, Good, Rossi Wannabe, to Riding God. It would be a nightmare to police, and perhaps insulting to some riders, and possibly (cough) seen as discriminatory.
While it is certainly insulting that the same approach has yet to be taken for car drivers, (have you signed the petition yet?) there are allegedly some moves being taken in that direction.
If I was 17 or 18 years old, I would almost certainly be raging about the clusterfuck that is current and future motorcycle legislation, but as a mature rider, I can perhaps see what is, in a misguided way, an attempt to save lives. I remember how I rode a bike when I was younger, and must admit that I am probably lucky to be alive today.
Young people hate being told "you're too young to understand", and I was no different, but with age comes wisdom (you'd think), and I would like to see some of our young riders grow up to be old riders.
