To be fair, that's not an argument on solid footing. Sure, courtship will be affected but with time, things will change and living with your parents will be seen as the norm, as it was with the baby boomer generation (honestly, why did that trend change? Idk). I've heard enough stories of grown boomers living with their parents and picking up their grown up dates from their parents' homes, in an elaborate courtship ritual that would sometimes involve her parents too.
