I feel like for this reason we should be focused on colonizing asteroids rather than the moon or mars. We can do various tricks to get artificial gravity via centrifugal force. For example if the asteroid is solid enough, we can consider putting it into a spin. If it's not solid enough, we can consider laying a track around the circumference and/or boring a tunnel around the circumference and essentially having the habitat(s) constantly rotating around the asteroid.
