Imagine all the children that age out of the foster care system every year, having missed the window of opportunity to be adopted as an infant. Imagine all the judgments and criticism one faces by being obviously pregnant and not returning from the hospital with a baby. Imagine all the guilt that gets piled onto an unwillingly pregnant girl who does not believe she is prepared to be a mother, followed by all the condemnation she gets for "giving her baby away to be raised by strangers".
Imagine the real world, the one we actually live in - not the fantasy world where all problems have easy solutions - before making short-sighted flippant suggestions that address the symptoms instead of the problems.
If the problems we face (society at large) were easy to solve, we would have already solved them. If all you have to offer are simplistic solutions to complex problems, try thinking a little harder.
