Congrats on getting to the magic 0!
I know it can seem weird that Europe didn't lock down over the summer, but here we mostly use Health care capacity, not active cases, as the most important number.
Being a relatively small island [0] on a remote corner of this planet makes the case for going to the 0 cases a viable one.
Going into a 4 month lockdown in Europe would be useless, since it would just pop up again since we don't have a few international airports as only places where you can enter.
So we're going into lockdown in Europe to prevent swamping our hospitals, and will resume life when it's okay again. And probably will keep going back and forth until a vaccine.
