> It seems like "abstinence is a birth control method"
Only with very very poor pattern matching. If people don't buy something, there is a 0% chance it will exist. That's better than any birth control method you might recommend.
You have correctly identified a flaw in the economic model you're using – although you missed the step where you look at the real world, and take note of the discrepancy.
In the real world, things exist that are not bought.
