From a quick search, the atmospheric density on Mars is ~20X lower than the top of Mt. Everest - the "dying zone". (And with the lower gravity, you'd need whole lot more than 20X, to get the same atmospheric pressure on Mars.)
20X'ing even a small planet's atmosphere is a big-ass ask. And if humans can only live inside pressure suits, or pressurized habitats on Mars - then "some plants can grow on the surface" is "that's nice, but...".
Hmm... Earth is much bigger than Mars, and has overheating problems. Gasses cool when they expand, per pV=nRT. In theory, if we exported a bunch of the Earth's atmosphere to Mars, we could kill 2 birds with one stone.
@xkcd, you want to take this?
