You seem to be making a bit of a meal of this. Yes, it's about safety, but it's also about making it as easy as possible to identify the different groups involved. It's not enough to say "I'm a safety conscious hobbyist", because I'm not aware of any hobbyists who doesn't think they fly safely and in control of their craft.
The issue here is that when you don't know about potential safety issues, it's very common for you to not know that you don't know. The point is that being unaware of a subject doesn't flag up something in your head that tells you what it is you're unaware of. A gap is a gap.
So, when the CAA (or other organisations) set up what appear to be draconian rules, it's largely about ensuring that people have actually been given enough information and training to make informed decisions about their safety, and that the authorities have an audit trail that show that to be true. It's just not enough to say "I'm safety conscious".
As it is, I think the CAA have screwed up. By not having a more accessible route to commercial operation, they've hogtied UK drone development, and the industry seems to me to be in a state of suspended animation - particularly when compared with the US and China which appear to be far more supportive of innovation in this area. I don't know what the answer is, but despite being great technical innovators, we seem to be sitting this dance out, and letting other countries develop drone technologies and benefit from the industries they enable.
That doesn't make it acceptable to ignore the rules, the reason for their existence is quite clear.
