> Make it illegal to transfer ownership of copyrighted work too, only the spouse or one single inheritor who isnt a company can have the rights transferred, after both die, the work enters public domain.

By your phrasing, it sounds like you still intend the possibility of companies owning copyrights; but how does that happen (other than copyrights already owned by companies grandfathered in)?

Copyright always starts off in the hands of individual human beings; it only ends up in the hands of companies when those human beings transfer ownership to a company. That ownership transfer can be automatic as a term of a contract, e.g. as part of a work-for-hire agreement. But no contract can cause the copyright to come into existence already held by the company instead of the individual. So if you abolish ownership transfer, you effectively make work-for-hire IP assignment invalid. What replaces it?

And, if "nothing"... then how do people pool the IP rights of their own small contributions to a large-scale work, into an IP pool that can be legally defended by a coherent legal entity, so that the large-scale work itself can have market value (i.e. so that sales of polished commercial bootlegs don't drive sales of the "authentic" work to zero)?

Keep in mind that, no matter how much we might want "mass distributed" media to have more-reasonable IP terms, the ability to sue for infringement is still critical to the existence of some forms of media. Especially "location-based" media, with no equivalent licensed broadcast right: movies still in theatre; concerts; live performances of plays and musicals; etc. If there's no legal team that can sue a movie theatre that shows an unlicensed copy of a given movie, then no movie theatre will ever bother with licensing movies again; "box office" goes to zero (from the movie company's perspective); and the incentive to create movies in the first place declines massively.

(You can see what this alternate world looks like from the few cases where movies screwed up the steps required to assert copyright, back before copyright was automatic. Night of the Living Dead (1968) is a good example: theatres — even upstanding large-chain theatres! — did indeed leap at the opportunity to show the movie unlicensed, and so Romero et al made effectively zero revenue off the work.)

I'm not saying this is an impossible problem. There are ways to accomplish this besides the way it's done now. (For example, individual-contributor IP could be retained by the original owners, but cross-licensed between individuals through a collaboration structure to form a coherent defensible IP pool, in exactly the same way that IP for e.g. video codecs is cross-licensed between corporations to form a coherent defensible IP pool today.) I'm just pointing out that the problem does need to be solved.
