I can't watch the video right now, but I'll comment on the headline. What I find intriguing is the age. Why 50? Why not earlier? The least thing men in their 50s are thinking about is having kids :)
Extremes are always dangerous. If it is unfair to force women to have children they don't want, it would also be unfair to force men not to procreate.
I do think that some measures should be taken to prevent unwanted children from coming to this world.
Education is key
