If a guy doesn't get given money for boats, what impact does it have on society? If someone doesn't get birth control, what impact does it have on society?
Don't have sex. You're a sentient being. 10s of millions of people stop themselves from having sex every day. Some have sex. Your choice. You're passing the buck. Your bad decision becomes my problem. Don't cause the problem.
Oh, yeah, and.... that's worked, hasn't it?
Oh, wait, no it hasn't. The abstinence without birth control form of "education" is the worst form of education.
Yes, people's bad choice becomes your problem. So, the CHEAPEST way of dealing with it is to have a targeted campaign of birth control. There's no way to solve this by saying "I don't want to pay for stuff", you pay or you pay more.
