Indeed! Although I'd frame Bir Tawil as a good steppingstone. Anyone interested in Mars colonization should first also setup a prototype Mars base in the interior of Antarctica. It has the same advantages as Bir Tawil, and it's still much warmer than Mars. If you can't succeed at Bir Tawil, you can't expect to succeed at Antarctica, and if you can't succeed in Antarctica, you can't expect to last on Mars.
