Every entrepreneur should also be forced to sell their business instead of passing that equity to their children. No more rent-seeking, multi-generational family businesses.
Matter of fact, let’s force the same on anyone with a 401k, IRA, or Roth as well because at the end of the day it’s all equity, right?
All equity stakes much be converted to cash upon death and either returned to the state OR given to charity.
That’s the way to make “Single serving wealth” happen and put an end to rent-seeking.
Meanwhile there's no effort involved in collecting royalties from your father's work, and no social benefits are provided by it.
That said, your comparison to forced confiscation of retirement plans by the state or charity is very strange, because it's not as if on your brother's death the state would come in and takes every cent he's ever made as a producer of IP.
In fact, the state literally does the opposite, and gives your brother's children and grandchildren the entire backing of both the civil and criminal justice systems. This is why we spent the 90's and 2000's sitting through VHS tapes telling us that unauthorized copying will be met with an FBI investigation, $250k in fines, and 5 years in prison.
There's nothing stopping an extremely successful and wealthy artist from handing down the money he made to his children. If they want to use that money to continue doing artwork in his style, using everything they have learned from him, there's nothing stopping them.
The point of copyright is to encourage more work. At this point he is rent seeking.
