i thought that to be the one obvious position. the other (imho) equally obvious position seems to be the following:

copyright is protection of intellectual property, and securing property rights is the prime reason for goverment to exist.

according to the second position (and taking opposition to the estate/death tax into account) it seems consistent with a libertarian position to argue for infinite copyright terms.

am i wrong? i am not a libertarian, but i try to understand you folks.
