Alaska is a big State. I mean really big. It is really hard to get any indication of what life is like living in this State when you are only getting to see one very small portion of it. Southeast Alaska is moderate temperatures and lots of rain. Northern Alaska is obviously much colder. Interior Alaska has some tremendous extremes in temperature.
More than likely, if you move here you will be living in Anchorage, Fairbanks, or Juneau (or one of the outlying areas surrounding those three cities). About half of all Alaskan residents live there. So, if this is where you are moving, you are basically living in a regular city with access to some really remote areas within a day's drive (well, not Juneau. Maybe a boat ride or a ferry ride and a day's drive). I've been in Juneau for about two years, and done quite a bit of travel for work, especially to Anchorage and Fairbanks. I can't say that I really felt like I was on the frontier or anything until I did traveling out the Dalton Highway or flew out to Kotzebue. Otherwise, it isn't that much different living here than other cities in the lower 48.
There are people here who have come to get away from everybody. It is pretty easy to do that if that's what you want. However, coming up here to "live" off of the pfd is foolhardy. You don't even get your first pfd until October of the year AFTER your first FULL year (resident as of Jan 1st), so most people are looking at almost 2 years without it. And even then, you are looking at maybe $2000 per person. Possibly less depending on how the State decides to balance their budget. The other problem is that being this remote also means everything is much more expensive. If you are looking at moving out to a village somewhere, you could be looking at $6/gal for fuel, $4/lb for apples, etc. It is not an easy place to live cheaply.
