“No current Beis Din is forcing all the single 30-40-50 year old men to get married, so the Halacha L’maaseh is not as you make it out to be. My opinion on the matter is moot.”
Winnie, no Beis Din is forcing people to eat kosher, put on Tefilin or give a Gett when halachicly mandated either. That’s because unfortunately Beis Din doesn’t have power today. A few hundred years ago in Europe and in the Levant our butei dinim DID enforce Halacha, as they should. The Halacha L’Maaisa certainly IS how I make it out to be, even if we don’t have the ability to enforce it.
That said, most frum Yidden WANT to keep Halacha. That’s why they eat kosher, wear Tefilin and give a Gett when required even if Beis Din won’t force them to. Unfortunately many people don’t always know what they’re halachicly obligated to do. Beis Din telling them will clarify it for them.
So too if the Halacha is that they MUST get married, and Beis Din so orders them, they WILL get married knowing they are halachicly required to as ordered by Beis Din, even if they don’t want to.
