They basically want to ban porn and contraceptives and abortion because they feel this will fix the decline of marriage as an institution. Basically, make the only possible way for someone to get sexual satisfaction stress free is through finding a wife.
But, the right wing really only cares about this for whites due to their falling birth rates. They think if they can get traditional gender norms back while killing immigration of non-whites (aka people from what Trump called "shythole countries") then they can get white women back in the kitchen and constantly pregnant pumping those white numbers up. They care less how this affects black folks.

This system requires workers and consumers.
If you have no people who are desperate enough to tolerate being abused by the public and by their workplace superiors, the service industry collapses.
If you don't have people with fukked up childhoods because they were an unplanned and unwanted pregnancy, then you get a decline in crime and consequently in police budgets since there's no point paying for cops if they have nobody to assault and imprison.
If you don't have women pumping out kids, you cut the profits of the entire child care industry. From diaper manufacturers to daycares(the latter operates on thin margins as is)
If you don't have young men desperate to get into college, the recruitment crisis for the military gets worse.
If you have less customers in general to subscribe to your service or buy your products compared to the last 20 years, you have no good news to share with the investors about growth. So they'll sell their shares and your company will lose money. You're already kind of seeing this now with a lot of big companies that just keep firing staff without severance and pushing useless products or hiking up the price of existing products. They're trying to make more money and make up for the fact that they have less people buying their shyt.
All of this relies on people, but more specifically livestock that can be used to do bottom rung labor, or minimally paid labor(prison) or defending the interests of companies that want to expand by grabbing resources from a weaker country(military).
A lot of people grew up with parents who clearly didn't want them, but they seemed to believe that if they never told their kids that they regret having them, that means that all the shytty treatment they gave them and their barely masked resentment of their own kids doesn't count. Republican parents are the fukking WORST for this. They teach their racism to their kids and they create c00ns with trans racial adoptions. They're restrictive, rigid in their mindset, delusional about the economic realities of the world and just generally insufferable people to be around because all they want is their existing beliefs validated by EVERYONE. They can't just be happy to think what they think and share space with others who think that way. They need to force YOU to validate their lifestyle choices.
