I owned a house on 60 acres in Washington State that was bordered on 2 sides by state land (WA DNR). It was generally great and the only time I closed my gate was actually these two weeks of every year for regular rifle deer season. I never had issues with hunters coming on my property (I did give some friends permission to bow hunt). My driveway was about a mile long and had to cross DNR land to reach my property, but I had an easement. The easements typically have a 35 year expiration and it would take extreme circumstances for the state not to renew an existing easement. Complete and total privacy is really nice, but it's certainly a lot of effort and money to maintain a remote property of that size with a large house. I had to travel to SF a lot for work and that was certainly not ideal: 2.5 hour drive minimum to a tiny airport that only served Seattle, then on to SF.
What would realistically be a ballpark expense for basic living (I assume you mean food water and power)
At 60 acres you can probably do a 3000 feet grass strip runway. Get a Cessna and fly yourself, being within flying distance of a tiny airport in this case is pretty awesome. 2.5 hour drive is ~ 1 hour flight time for your C172s.
