Congress has currently chosen a duration of life + 70, but my point is that it's absurdly far beyond anything necessary to encourage the production of new works. When you consider the costs of copyright monopolies to the public, it's clearly out of whack. As I said, the majority of revenue from copyrighted works happens in the first couple of years of release.
I completely agree that life+70 is absolutely obscene, as my response to your parent post clarifies. I moved on from that since I thought my stance was clear (14 + 14 or 28 total), and moved on to “we should still honor the copyright even if they die, because heirs matter.”
NEVER have I argued for life+70 and I never will.
