There is nothing saying that you couldn't make a living off of improving grapes, though it would admittedly be more difficult. At the end of the day though, I am far more concerned about food security than the right of people to profit from IP. You can't simply wave the problem away by stating the state can take all they want. Many democratic states would be hesitant to do that and it would have far more grave long term consequences. If agriculture was more diverse, perhaps that wouldn't be a concern. The problem is the lack of diversity creates the potential to concentrate power over the food supply under the current model, never mind one with strong IP rights.
