I think we can align on the lack of evidence presented. There is also the question on what agreed to means in this sense.
In terms of public opinion, it would be interesting to know what studies have been done. I imagine if you would get broad support for an author copyrighting a book, and less on patenting a pre-existing genetic sequence.
As another unsubstantiated claim, I think if you sat down with the general public and the criteria for patents, they would mostly agree.
The challenge has to do with implementing them and the legal process around them.
If a crappy patent is issued to large corporation, it is incredibly expensive to challenge them.
