Under the law, machines are not able to create copyright, and basic human involvement is not enough to change this. Eg if you click a button saying "go", that won't create copyrightable content

You can use all the ideas you want, but AI cannot because its not a person, and does not enjoy the same protection under the law. The copyright holders by and large did not agree to you using their content like this

If we enable this, people won't create anything because all their work will immediately be stolen by the AI models. Copyright partially exists to promote the creation of new content, because theft disincentivises novel creation
