Second of all, majority of US population is urban. People in NY or Bay Area can't elect a president who represents their interests due to how Electoral College is designed but attempting to change their opinions on having children by banning porn is a pipe dream.
US population is growing for a combination of immigration and just slightly better birth rates than others. It's nowhere close to above-replacement levels (2.1). Just check out the population pyramid, and you can see there are less younger kids than older ones.
And almost all growth is immigration, the fertility rate hits new lows constantly.

“U.S. Fertility Rate Drops to Another Historic Low”
I'm increasingly convinced that the goal is to balkanize the US and establish a Network State guided by silicon valley, as described by Curtis Yarvin
The problem has not been solved, and all western governments are hoping to delay the problem through immigration. This buys them time to see what solution Japan, SK and China can come up with, and copy that instead of taking risks with potentially abysmal results.
I doubt banning porn or abortion or engaging in cultural engineering will fix this.
And then there's this phenomenon, discussion of which was once verboten in goodthink circles (like HN) due to its anti-feminist and "incel" optics, but has since grown enough in strength and scale to shove its way through the Overton Window so that even respectable, MSM sources cover it: https://thehill.com/blogs/blog-briefing-room/3868557-most-yo...
What you need to have a modern, western country instead of a dog-eat-dog wild west is welfare, including universal health care.
But welfare is considered as an evil communist plot in the US and the people who are led to believe that they are somehow above the working masses keep voting against their own interests. Not just in the US, unfortunately.
The best way to have more kids, unironically, is making everyone as poor as possible, removing any other method of entertainment, and making "having kids" the only choice. That's how it worked for the eternity, and some people want a percentage of people to go back to it, so it would support the current established system.
That's proably a non-insiginficant factor but unlikely to be the only one. Poorer people have never had problems reproducing in any society.
I think media exposure plays a much bigger part. Not porn exactly, but anything that glorifies a "free" lifestyle over settling down.
The "Birth" lobby is a stool composed of several legs:
1. Attack abortion
2. Attack contraception
3. Attack porn
4. Attack education
5. Attack "women in the workforce"
All of these things are seen as contributing to declining birth rates, so they're opposed by Big Birth. You can see the same politicians tend to go after these things in lock step.
There’s a very obvious “pro-religion” push going on across all social media as well, but it’s hard to pinpoint when/how it started. Not sure how far they’ll have to roll back women’s rights to get where they want to, but it’s incredibly sad to watch. Not sure how fathers with daughters are going to watch this happen in real time as well.
