You are just deliberately misunderstanding. You can argue for IP if you please but please don't pretend that IP and property share anything but an analogy. Just because information can be used to describe anything doesn't imply that physical things and ownership tags on patterns of bits that decode to tagged patterns are even remotely the same they are actually in opposition.

Physical things are scarce thus we are face with the inherent choice of deciding whom has the privilege of eating a sandwich or living in a particular house. The method of distributing goods is often capricious, unfair, subject to every existing bias but at least it represents a choice we must make. We can't both eat the whole sandwich.

A pattern of bits isn't a physical thing in the same class at all it is a restriction on which bits 2 parties unrelated in every fashion to the creator may transmit between each other. It's not a sandwich it is a recipe. It is granting a singular owner the privilege over say the concept of ham and cheese on white bread and demanding that people not make each other sandwiches that are identical in construction to the "owner" of that recipe under the theory that this will encourage people to develop more new and exciting sandwich types.

We aren't throwing ownership out the window. In fact traditional ownership never came in the window in the first place its a mile up in orbit. What you are arguing for is an entirely different class of thing in need of its own thought process and justification. If you are going to justify it then it must necessarily be on its own terms with its own implications not by leaning overmuch on traditional property.

Pretending its the same leads to many logically nonsensical things like Sony Bonos widow suggesting that copyright ought to be forever like owning a house so that the numerous and useless great great grandchildren of the creative who have nothing to offer us can tax all of creation to pay for the drugs they will probably end their pointless lives with. All of art is derivative thus endless copyright would cede all of the creative universe to the heirs of the current creative class who weren't burdened by paying tax to their predecessors. Alternatively logically nonsense like eventually all common reasonable arrangements of notes belonging to somebody.

The truth is copyright was invented as a tax on society to gift to the rich and useless and only then adapted as a method to ensure publishers paid writers in an era when printing was expensive. Even now most of the money sticks to business people not creators. We would be well rid of it.
