Not “instead of” but “in addition to”. Government regulation is not perfect but is the first-best solution to imposing such injunctions, and prima facie is much more effective than social norms or industry self-regulation. That’s a major part of why the industry bodies are objecting to it.

This is the fundamental tension in law making and government in general.

Leaving room for nuance reduces the seeming capriciousness seen in the enforcement of some laws that look heavy-handed when applied strictly, while said underspecification can allow for abuse instead.

As long as people are individuals with their own volition this tension will exist.
