I think I have read this article before, but I really ought to get the book that is referenced here and try reading it and see what it’s like. I think the Free State Project is still around, but I’m not sure. However, even if it’s not, I know there are still quite a few libertarians living in New Hampshire that moved there for that reason, and so it would be by far the most libertarian state around. Take a look at free talk live and the porcfest and forkfest as examples. They have New Hampshire branded goldbacks, Use gold and cryptocurrency as money, And generally get arrested for activism for telling the government that they are A bunch of murdering psychopaths.

Edit: NBC Boston did a documentary about them rather recently.
