In the context of copyright law, this is absurd. Fair use exists and it generally isn't even required to "allow" artistic and cultural influence to propagate. If I want to write a sci-fi novel that is heavily influenced and arguably even derivative of my favorite work of some other author, I am completely free to do so---i just can't copy it wholesale. Established fair use doctrine is certainly subject to criticism and future reform, but in a much more nuanced scope than you are applying here.
If you're talking about patents, that's a different conversation. But based on context, that isn't the conversation we're having here.

Generically, this is another common suggestion from people with naive viewpoints and little or no relevant experience and/or exposure. Notably, people said that about both of Trump's presidential terms to date. I will let you make up your own mind on how that is going for us.
edit: I should also mention that literally every working artist I've talked to about the prospect of abolishing IP law is vehemently opposed to it.
