Are you opposed to all kinds of intellectual property protections or just this one domain? In particular, why should anyone put R&D into developing better varieties of crops if their innovations aren’t protected? Or perhaps improving crops (to be more drought resistant or to produce higher yields) doesn’t strike you as important—if so, how do you suppose we produce the additional food to sustain our growing population, especially in light of climate change (reduced land, increased droughts and other causes of crop failure). I don’t know about this particular case, but I wouldn’t rush to advocating for zero IP protection for crop varieties.
I'm against all kinds of IP. The government does not have a right to tell you what you can do with your own property.

Why should people write free software?

Population is nearing or below replacement in developed nations. We don't need to produce more food, we need to stop exploiting developing countries so their standards of living increase.
