It's better economically and for productivity for people to not have HIV, Syphilis, etc.

Stop this. It isn't an economics issue. This is a moral issue. Your tract of reasoning is precisely why the world is growing so untenable for the human element. There needn't exist laws or programs or any other edifice by which regulation is effected. People need to be made to realize that they're being wholly indiscretionate and their disposition to do so comes at a cost, and it should be personal to make the point manifest.

With all due respect, the first half of comment is literally prefaced with "the moral argument". Personally I believe that argument should be enough, but you gotta play to the audience.
