The reason is even simpler. Antarctica is like a self destruct button for the planet. They don't want people going there because a few people with a paltry amount of money could kill billions.

It's kind of hard to explain but theoretically a person with a large amount of coal dust could cover several hundred acres of the permafrost, making it blacker. This would cause it to absorb a bit more sunlight and heat up the ice just enough to cause breaks. You would get ice bergs the size of countries. It would completely fuck up the environment and there wouldn't be a way to fix it.
