On this side of the wall, you and your friends are strong and happy and free in your garden. On the other side, a hellscape filled with giant monsters debating how best to filet you. You will keep ceeding them ground, your garden gets ever smaller. The monsters ate Brian, oops, well that's the consequence of freedom! But you're next, isn't it completely obvious you're next? Why would you unilaterally disarm against the monsters? Why for the love of God why would you say "no the monsters are good actually!"
