You should look at it through a more utilitarianism POV. If your country gets invaded, not only do you loose your way of life, culture and society get impacted to the point where you won’t be able to continue as normal, but the environmental destruction of war in your own country far outweighs what the gerontocratic part of your society does today. You only have to look to Ukraine for that.
So it might be more advantageously to voluntarily undergo military training, so that in the event of an invasion you can try to defend your way of life and continue to strive for a more equal and environmental conscious society after the war is over.
