From my perspective it offers less. For instance, holding a passport from nearly any other country is effectively like holding a form of health insurance - if you get diagnosed with a long-term disease like cancer, you can repatriate and get free treatment. Not so with US citizenship.

Yet other countries don't charge for this much more tangible privilege.

The US passport also isn't even in the top 10 most valuable ones to hold for travel https://www.henleyglobal.com/international-visa-restrictions...
