If I do, then sue me for doing so. If the system fails to provide you compensation, then the problem isn't that I planted the crops that contaminated yours, but the judicial system that no longer functions. In that case, you have lost your right to your property. Unfortunately that is the place that you live in. As time goes by you lose more and more of your rights, eventually you will have none.
So remember, the problem isn't that another farmer planted corn that pollinated with yours, but that you were unable to be compensated for the damages. Preventing me from planting corn on my field will only take away my right to my property. In the end not only do you have less rights, but so do I; and guess who has that right that we lost...the government.
