Everyone just stays inside pretty much. As in… 99% of the population lives in a city and there just aren’t any snakes.
There’s a bunch of other reasons too though. Snakes are reclusive by nature. They’re well camouflaged and easily hide themselves among leaves and bushes and plants on the ground. They actively avoid being seen by humans, they do not want an interaction with a human because it will always be a negative outcome, in that they can’t eat a human.
You could walk 10km through the bush, be reasonably observant, walk within 2m of a dozen snakes, but not see a single one.
OTOH there’s mountainbike trails where you’ll encounter several in a day. You’re moving quicker, and they can’t feel your footfalls so don’t have time to hide.
The thing is… 99% of the snakes I’ve encountered are deadly venomous. We have pythons but I never seem to see them. Here it’s always Tiger snakes or Dugites which are both “stop moving and call an ambulance” type emergencies if you get bit.
Yes it’s a reasonable request, but it’s also pretty meaningless.
It’s performative. Like if you break this pledge nothing happens.
However, it’s performative in the same way that a marriage is really. I mean you can go to the court house and register your marriage without having a ceremony, but that’s very uncommon and in the vast majority of cases you have a ceremony and do all the things.
Achieving citizenship is an important moment in anyone’s life. If your own case for example your Mother’s citizenship ceremony marked the point at which the work to change the trajectory of her life and all of her descendants had achieved the objective.
A little pomp and ceremony doesn’t hurt.
