I can see the opposite argument made for copyright that if someone can coast off the success of their first work that in and of itself can de-incentivize them from making anything new, this is why movie companies just remake the same movies and stories every few years, it's to coast on the success of the old one, and this is even a problem with shorter term copyrights. Their limiting factor is with the technology of the time making the old ones look dated, not so much the copyright expiring. If it didn't look dated, they would just re-release the same ones over and over and over again.

Copyright was made for Joe, or a small business, but applying that to a big business doesn't work, and is in fact a bad-faith argument, trying to tug at our heart-strings to make us feel bad for someone that we shouldn't feel bad for. If Disney couldn't sue people for copyright infringement they'd still find a way to go after them, they have more than enough money to hire a PI to ruin the person's life, or you know just hire a hitman. It doesn't do anyone any favors to Compare Disney, Paramount, Amazon, Facebook, or Google to a small business who needs our help to not be screwed over.

Ironically in this day and age it doesn't do as much for those small businesses anymore because they don't have the money needed to fight those claims, you know who does though, the big ones, the ones who don't need protection at all. They're free to predate on these smaller people if they choose, and those smaller people will be otherwise powerless to fight back, and even if by some stroke of luck they do, it'll likely bankrupt them because of it.
