I'm not sure if you're trolling or not, but what the hey.
Many inventions, even some of the best, are only obvious after you've seen them. Hindsight is 20/20. How many times have you seen a new product and said to yourself or someone else: why didn't I think of that?!
Does that mean that none of these are inventions that are deserving of patent protection? The consensus among people who think about these things is: no, obvious in hindsight isn't a good reason to reject a patent. That's the rationale. So, I guess there can be one.
So, how do you decide what would have been obvious to someone who was thinking about the problem, without having seen the solution, as you now have? These tests are how the USPTO tries to answer that question.
Finally, what makes you think patent lawyers are ignorant? By definition, all of them have a technical degree or university-level training. Many practicing in the biochem field have advanced degrees. PhD is almost a requirement for entry. Many were also researchers before making the transition. Patent lawyers have a much older average starting age than your prototypical lawyers. Heck, I know one who was a tenured university professor for 20 years before looking for a new challenge.
Your post reads to me like the simplistic reaction of someone who's spent maybe 2 minutes thinking about this in the last month -- and both of them after reading this article. I could very well be wrong, but then I'd say you're just poor at communicating.
