Isn’t the issue more that Mars does not have a tectonically active core, such that it does not have a protective magnetic field like earth. Any water we put on it will eventually get blown off by solar wind just like most of its it’s original atmosphere .

Eventually, yes, over multi-million year time scales.

Actually, NASA have figured that that placing a sufficiently powerful magnet in orbit at the mars L1 Lagrange point would be enough to act as an artificial magnetosphere and protect mars from the effects of solar winds
