The Great Uterine Conspiracy

Governments need to legislate against birth control options, because they know that if women actually have a choice in the matter, they know that the human race would be doomed to extinction. Because if we can't trick women into having babies through ignorance and lack of intention, then what chance do we have? Women, if given the chance, will lock their uterus down with so much baby-preventing chemicals that the only hope will be funding the construction of mechanical incubators - and do you know how expensive that would be?

If it sounds dumb, think of any given rationale that politicians give.
