This is not going to stop porn. All it will do is criminalize the actors, producers, and viewers.

I'm reminded of the drug war, where they took a relatively harmless narcotic used disproportionally by minority populations at the time (Marijuana), and used it to criminalize and imprison large swaths of the population, especially within the black community.

It's no coincidence that most of the folks targeted by this effort are women and sex industry workers, which skew liberal by a large degree. Note I'm not just talking about prostitution or porn actors, but the entire sex industry, including toys and books.

The GOP is scared shitless of the rising power of women in modern society, and being able to criminalize and consequently attack the revenue stream of sex industry workers is a way to blunt it. There's also an element of class warfare involved, as OnlyFans or similar sites are often the most economical way for a young woman to lift herself out of poverty if she has no other marketable skills.
