I assure you Pork, there are a lot of things the 'free' insurance doesn't cover and having other insurance is a good thing if you can get it. Need glasses, braces or other major dental work? You're on your own.  Need to travel? Unless you have Medicaid, you're on your own and even that is limited.  Travel outside of Alaska and want medical help? You're on your own. Lots of people assume things they know little about.
