By making condoms free, we would be both increasing production in the birth control industry and providing easy access to a simple form of birth control. Condoms are small, simple and easy to use. They can be carried by nearly every basic grocery or drug store supplier, and only cost around a dollar each. It's a win-win. Free condoms are also a much easier debate than free birth control pills, IUDs, or implants. They are not surgical, they are easy to understand, and almost anyone can get them.
Condoms still cost money to create, and unless stores are being given condoms to give out for free, cost money to place inside stores. We also cannot trust that people would not steal these free condoms and attempt to turn a profit, taking all of them and trying to sell them.
[P1] Condoms are easy to access and cheap. [P2] Condoms should be free.
