I don't pilot the planes I fly on - and I extend that exact logic to cars/trains/ferries/boats and ALL other transportation. This applies especially planes and domesticated transportation like camels and elephants. I've haven't had the need to ride a llama/alpaca (yet), but it would apply to them as well if the situation came up. Bicycles, 1-man canoes, and horses are really my only exceptions for obvious reasons.
You really can't take your car heliskiing. And you still need a bush pilot in most of the semi-remote world to get around.
I take your point but, for most people, there's a lot of ground between hiring a helicopter to go heliskiing and being dependent on whatever public transportation happens to be available. Clearly we have different lifestyles. Even leaving aside that I couldn't easily work at my current job without a car, I'd have to give up a significant subset of my recreational and travel activities.
I have never been to US national park, but I've visited some in Eastern Europe and Scotland. I can't imagine myself traveling over 4 thousand miles by any other transportation (trains, buses, bicycles, walking) within given timeframe, budget and convenience. Now this is the "old world", where you travel 500 miles and find yourself in an another country; I can only imagine what traveling in the US feels like. Maybe, one day, I will know - one can always hope...
