The reproduction is, possibly, tangible, the IP itself is not - you cannot touch an idea, only what is generated BY the idea, sometimes...

I'm sorry, but a song is not an 'idea'. It is a tangible composition, just like a play or a novel.


“... if the IP cannot be transferred, it cannot be stolen...”

That just doesn't make any sense. That happens all the time.


“One point where I think we do differ is when something should enter the public domain. I happen to believe that a rich public domain is a benefit to all society, my preference is 25 years after the death of the artist, not 25 years after the first publication as it was at one point. This gives the artist an income for his/her lifetime. And when one considers how short lived most songs are this should be ample.”


Once again, you might feel differently if you had spent your entire life trying to write a successful song, or play, or novel. It requires the sacrifice of time, work, family, friends and money, all with no guarantee of success.
Frankly, I'm not ready to surrender my rights to you or anyone else to satisfy your desire for a 'rich public domain'.


“Another point, when does a corporation die? If a copyright holder is a notional, legal entity that cannot die then just when can anything enter the public domain - this is bad for society as a whole as it basically kills the sharing of ideas.”


If the song is my property, I have the right to assign it to whoever or whatever (in the case of a corporation) I choose. Songs owned by corporations are still bound by the limits of the copyright laws.


I don't write to 'benefit' all of society. No one does. Without the incentive of profit, your 'public domain' would be devoid of any decent art.
