I am fairly supportive of IP law in general, but I don’t believe that the creators of Friends would have passed on making on the series if they were only going to able to monetize for 20 years.

20 years out at only a 5% discount rate pa is a 65% discount. At a more reasonable 15% discount rate for a proven show, you’re left with under 4% 20 years out. For an unproven pilot, you probably handicap that significantly more.
