There's actually much more to it than the tax benefits. Married couples have the legal right to speak for their spouses in things medically related. There are issues surrounding inheritance when a spouse passes, joint ownership of property...
Imagine owning a house for years with your spouse, making it a home, growing old in that home... Your spouse passes, then your brother in-law files suit because as the closest-living relative, he should inherit.
It's not just taxes, and it's not to stick the proverbial thumb in the church's eye. It's about fair treatment in how you live your life.
