I don't want to belabor the legal issues here, but I think that your point still needs to be addressed. If I'm understanding you, the subtext of your reply is "how can I get the permission of someone who's dead

If the copyright is allowed to expire then the work goes into the public domain.
And no, I don't own 27 pairs of sweatpants.
