Creative people should be able to create. Trademark/copyright laws, protecting assets for the great-grandchildren of who actually created the art, has never been a positive. The only people who benefit, are themselves not creative (or else they would create, instead of defending "rights" and "image").
Trademarks benefit people - see my explanation in a different response to you.
And seriously wtf why shouldn't, like, Jack Kirby's grandkids get a share of the huge bounty of stuff he created for Marvel, but Elon Musk gets to inherit emerald mines from his dad?
If you feel that your idea is worth IP protection, just protect it as a trade secret, not as a patent or copyright. Very famously Disney have a copyright over drawing three close circles.
Limit IP laws to 20 years.
Humans go from birth to being released into the public domain as an adult in roughly that time. Why are ideas somehow not in the Public Domain after a generation has grown up?
That way Jack Kirby gets to make his money. Jack's kids can live off his money. But Jack's ideas are free to use after doing their time.
