As an author, a creator of intellectual property, I strongly disagree with you. Why should my property rights to my intellectual property creation disappear with my death and my heirs, my children NOT get my work that I have worked hard to create with my imagination and skill and built with the intent that it be passed on to them merely because YOU want it without having worked for it? Why should you have for free what I worked for? Why should my children be taxed of their entire inheritance because YOU want the free use of it? What a socialist idea.
And why shouldn't the same idea apply to patents?
