I think it says something quite dark about our society as a whole that we have basically commoditised distress and are encouraging some people often themselves in dire circumstances to prey on others to the benefits of the middle men. I find these new pimps scarier than the old sort in that they pretend to have clean hands.
Vices like gambling, obscenity, prostitution, drugs, etc are banned or heavily controlled societies over because they have significant negative cultural effects. “Why do YOU care what other people do in their private lives?” was always a stupid justification: if everyone in your community is addicted to vices, that DOES affect me.
Do they? Citation needed. So far it seems that marijuana consumption leads to far less violence than alcohol, and proliferation of porn leads to much lower rates of sexual violence.

Then choose and manage your own community, but don't push this view on the whole country. Dozens of millions of people (I don't know what country do you live in, so not sure about the population) are not a "community" that you can put under the same norms. If you think that porn is bad, it's your right to do so, and to find likeminded people to build a community that shares these values. But why would you want to force it on other people?
