I can't downvote you, but I presume that you're being downvoted because your comment seemed to not understand the context of the thread.
A. Someone proposed making copyright "use it or lose it"
B. Someone else said this could have unintended consequences, like people breaking into your house to take a copy of a work where copyright has lapsed.
C. I pointed out that's not how copyright works: it has nothing to do with control of physical artifacts.
D. You then presumed that the copyright runs for a long time, which contradicts the premise we're talking about in "A", and is completely out of left field. (In any case, it's irrelevant to the question in B-C; if I have the one of the only extant copies of something from a century ago, you still can't come take it to make a copy).
