I don't know how any of the proponents can pretend that this isn't an abject disaster on the horizon for anybody who depends on copyright to make their living.
This is the natural progression to the unnatural properties of the shared delusion of pretending like ideas are property or that it every was natural to keep them artificially scarce. If we lived in an ideal system where ideas are free, copyright didn't exist, and artists and programmers could survive and thrive without the ability or need to hoard their work as if they were physical goods, this would be a non-issue. The system was antiquated for the needs of the modern world for multiple human generations already, and this is the dam breaking.
