That was 6000 ly away. If another one happens 3000 ly away, whatever water thickness you cover your entire Martian base may easily not be enough. Or 1000 ly. Or 100 ly. You can hope but you are still rolling dice wherever you are in solar system or out.
If you want to protect humanity's survival from gamma rays, you can add the same protection on Earth more easily. The rational reason to colonize Mars is so that you can escape there when things go bad on Earth. Which is especially funny because the 1% who escape there are the ones responsible for most of the pollution right here.

On Mars, where the atmosphere is already toxic, this would be irrelevant. And there's no way to shield Earth against this at all. And nobody's going to be escaping to Mars. The wealthy and powerful already have their doomsday bunkers and hideouts; even a post-apocalyptic (such as after WW3) Earth would generally be a much more hospitable place than Mars will be.
