But the oft-touted "Joseph & Mary" marriage had a purpose.
They were tasked with being the mother & foster father of the God-man, while also keeping the glory of perpetual virginity.
Jesus wanted us to have a model family to emulate, with a father & mother. He also values virginity, which is something the sex-crazed modern world can't comprehend. "And the darkness could not comprehend it."
That having been said...
My view, which is quite based in Catholic doctrine, is that Josephite marriages are NOT what the doctor ordered for the modern world today. In fact, they are the exact opposite.
What the world needs today is FECUNDITY and lots of it. They need sacrifice-minded MEN and WOMEN to live their roles as God intended, and make whatever sacrifices are necessary to have as many children as God sends. Through hard work, sacrifice, and much trust in God, it can be done.
The modern world thinks that children are a burden and a punishment. Contraception, fornication, and abortion are rampant. Marriage has become a joke. Children are spoiled; foolish moderns think that each child costs $180,000 to properly raise to adulthood.
What the world needs to see today is the example of countless Catholic families, the husband and wife faithful to God and to each other, loving each other and their children, working hard and trusting in God, raising whatever children God sends. People need these living examples. When people notice a family larger than average (more than 2 children) it gets their attention. It makes them think.
If a couple DID successfully pull off a Josephite marriage today, they would appear to most men to be just another "DINK" (double income no kids) couple -- one that values wealth, pleasure and travel, and doesn't want the burden of even 1 child.
What kind of good example could they give to the modern world? Who would even KNOW that they're both still virgins? I just don't see the benefit.
Yes, God would see their sacrifice -- but even then, they would do better to consecrate their lives in holy Religion, so that their every action (washing the dishes, for example) would be an act of religion. We shouldn't forget the valuable role the Religious play in the economy of salvation.
