Pros: none

Content label doesn't transform the content. It just provides a false sense of category.

I still have to think critically whether there is a label or not.

Cons: New ways for sociopaths for corruption, embezzlement and censorship.

That is my point.

This idea that legislation has no downsides is extremely naive and borderline retarded. Look at proposed legislation from the point of someone who wants to destroy everything. Does it provide a path to that goal? Is the risk worth it?

Every government grows over time and produces more and more suffering while consuming more and more wealth. I recommend reading The Gulag Archipelago. Your thinking seems to be dangerously naive to you and people around you.
