Perfect example of this is the movie Dogma. Kevin Smith has stated he would love to do a follow up on it, but he as the creator can’t because the IP is owned personally by Harvey Weinstein, and he refuses to give money to Harvey to license or buy it because obvious reasons. So, his own creation is locked away from him because a monster put up the money for the original before Kevin or most people knew they were a monster.
Generally speaking yes, but there are some exceptions.
For example, flashlights intended to be attached to a firearm DO incur a premium for a good reason. They’re subjected to intense sudden movement and vibration, repeatedly, and it takes a lot of extra hardening and redundancy to develop a light that can repeatedly withstand that kind of abuse without eventually knocking core components loose. If you were to try to attach a tactical light intended for airsoft/bb use to a real firearm, its not going to last long. There’s a reason gun lights are as expensive as they are.
