I would challenge you to first propose a structure that somehow compensates people who create artistic works now to be able to do so in the future without subjecting them to a patronage system.

Figure out how to fund research that doesn't need to rely upon licensing of patents.

The bold statements of "eliminate copyright and it will solve {problem}" without the corresponding steps that you would need to get there are intellectually dishonest and ignore the current economic system and wellbeing of the authors and artists who produce work.

I would also note that I do value the software freedoms and without copyright there would be no way to enforce the redistribution of the source and the improvements that a company makes on it. "Here's the binary, but good luck trying to back port the bug fixes we did" is something that the licensing that copyleft provides.

The approach of "burn down copyright and something wonderful will emerge from its ashes" is not a convincing argument.
