It is entirely unreasonable to prevent a general purpose model to be distributed for the largely frivolous reason that maybe some copyrighted works could be approximated using it. We don´t make metallurgy illegal because it's possible to make guns with metal.
When a model that has this capability is being distributed, copyright infringement is not happening. It is happening when a person _uses_ the model to reproduce a copyrighted work without the appropriate license. This is not meaningfully different to the distinction between my ISP selling me internet access and me using said internet access to download copyrighted material. If the copyright holders want to pursue people who are actually doing copyright infringement, they should have to sue the people who are actually doing copyright infringement and they shouldn't have broad power to shut down anything and everything that could be construed as maybe being capable of helping copyright infringement.
Copyright protections aren't valuable enough to society to destroy everything else in society just to make enforcing copyright easier. In fact, considering how it is actually enforced today, it's not hard to argue that the impact of copyright on modern society is a net negative.
