Well, our governments "produce" quite a bit, actually. Especially when federal and state coordinates for the greater good of our
United States. Interstate highways, Intercoastal Waterways, National Parks and Wildlife reserves, regional and International airports, standards for public health (CDC and those mandatory vaccinations for measles
) and food safety, national standards and reciprocity for education.
Freedom of mobility with continuity, that's what government "produces". One driver's license and one HS diploma can take us from coast-to-coast. We can transfer between public schools from any state, in any grade, and not have to start fresh in 1st grade. Everything from our state K-12 graduation, to universities and accreditation "produces" a coordinated effort we'd be hard pressed to find from any private entity.
We all use the same money/currency. We have protections of our US Constitution and SCOTUS when state laws and constitutions may disagree. That "produces" a unified approach, where our freedoms aren't restricted within our nation's borders. It's not perfect, and things like marriage and sexual behavior are still being debated between state legislatures. But I'd say, overall, our governments can "produce" quite a bit when it comes to protecting our Liberties.
