To be totally honest, I am fine with the situation you just described. The only argument in favour of IP is "but what about the economics of the seeds?" i.e. "but how will corporations get rich without it?" and my answer is: they will have to find some other way to contribute to humanity than placing a stranglehold on the freedoms of the poor. Edit for those whose rebuttal is all too predictable: I know this affects the incentive structure for developing new science. But I don't think it's at all clear that the current incentives are actually a good thing in the long run. Alternatives for income could be one of the following: providing a service, producing and selling the seeds, working with local farmers to help them maximise yield from the seeds you developed, securing donations from those who stand to benefit from your research... etc.
