You have not supplied a reason for why we should have copyright. To say "Copyright exists because it gives the right to copy" or "Copyright exists to monopolize copying things." is begging the question. It doesn't tell us why recognizing such a concept is desirable. Best you said is, "A thing like copyright is needed. Falsely attributing the creator is problematic" which is a good start and only that.
And this is really about intellectual property, which copyright is one type of. "Copyright is valuable because it restricts copies" is not a particularly useful observation in the age where authored works can be digital. The history of book printing can only guide us so far. Why should intellectual property be protected?
Yes, any answer to that question WILL be an opinion. There is no avoiding that. It is fine to shoot down others' opinions but can you give your own?
Why should society care if false attribution is going on? That's just the author being arrogant enough to think their work is important enough to be setting standards, right? Why should society care if someone is upset that their ip is being used against their consent? Until you can answer that, you are still avoiding the question.
Or should we abolish intellectual property? Would it be a better world if everywhere was like China?
