Destroying the family unit just promotes shallow hook up culture (think modern online dating) while destroying any form of loyalty.
What we're seeing now is a direct result of destruction of the family unit. A good way to destabilize countries is to destroy the family, i think social engineering is working over time to achieve the exact goals you state.
I guess maybe this can be a good thing if you believe in the chaos theory, but even if it ever reaches the point where society collapses people pulling the strings will be all over it to control the outcome, which sure as hell won't be in are best interest.
