Again, this link gives a pretty thorough depiction of the practicality of mounting a mission to Antarctica: https://www.youtube.com/watch?v=NPbhHpeHTiE
Cliff notes? Sorry, not watching a 30 min video right now, especially if it boils down to "Antarctica is cold and inhospitable, making going here difficult" because, well duh. Again, with the proper funding, and reasons within the bounds of the treaty, you're free to go there. The fact that the former might be in the hundreds of thousands of dollars doesn't change this fact.
