There are legal definitions of advertising, I’m sure the courts will be able to figure it out.

The "legal definition of advertising" is the thing you have to write into the law you want to enact. If you can't answer the question as the proponent of the proposal then how is a judge expected to do it?

What the parent is getting at is it's not a mystery, such definitions already exist in all kinds of jurisdictions.

In any case it's trivial to come up with such a definition that covers most cases. Doesn't matter if it doesn't cover some gray areas or 100% of it. Laws can be supplemented and ammended.

We don't have an all-encompassing definition of porn either, but we have legal definitions, and we have legal frameworks regarding it.

That's exactly the thing that matters when you're dealing with something where every loophole is going to have a caravan of trucks driving through it.

You're picking the thing which is a hopeless disaster as your exemplar?

Everything with profit "is going to have a caravan of trucks driving through it". He have laws anyway for those things, and for the most part, they're effective. I'd take a relative improvement even if it's not 100% over free reign.

>You're picking the thing which is a hopeless disaster as your exemplar?

I don't consider it a "hopeless disaster" (except in it's effects on society). As a business it's regulated, and for the most part, stays and follows within those regulations. The existence of dark illegal versions of it, or exploitation in the industry, doesn't negate this.
