Snares already exist, with scrap metal and metal shard. They're basically bear traps that snag whatever steps on them.
The animal traps, as of now, are cheesy in that they generate meat every 2-3 minutes. They simply snap closed whenever the timer is up and you can take out a steak.
There needs to be requirements, like the trap not working at all if someone comes within 100m of it for like 5 minutes or something.
As it stands, people are building bases and loading up the base with traps inside that automagically generate meat so they don't have to forage for food. The smart players are building their base around wells, too, so they don't have to scavenge for water, either.
