The drastic measures you mention could be as simple as NOT teaching our children from Day One that it is so assur and untsniusdig to talk to the opposite gender, that they must always be segregated from each other, rather than having mixed properly supervised events where they can meet and socialize.
And none of us can presume to know who will get Olam Haba. I think the emotional onaa that this “project” is putting on financially strapped people, would suggest otherwise to me and to a whole bunch of people whom I know, who have been floored after reading of this “innovative idea.”
