Let's dive into implementing Conflict-free Replicated Data Types (CRDTs). Since you're a seasoned engineer and keen on travel, let's mimic a travel scenario where users can constantly add and remove destinations from their bucket list.

For instance, if two users are accessing the same list from different devices and add a destination simultaneously, there can be conflict reproduction. That's where CRDTs come in handy, ensuring our bucket list data is replicated consistently across all devices without conflict.

Below you can find our hypothetical 'Bucket List' represented as a Python Set, which we use to mimic the CRDT implementation. Sets in Python are similar to CRDTs in that they can handle additions and removals without worrying about the order of operations.

Our code snippet first constructs a bucket list as a set. Then it uses a function to simulate adding and removing destinations. The:add_destination function takes the bucket list and a new destination as parameters and includes the new destination in the list. Similarly, remove_destination function takes the bucket list and an existing destination as parameters and removes the destination from the list.

In a real-world scenario, these functions would be called whenever a user adds or removes a destination from their bucket list on any device, ensuring all changes are reflected consistently across all devices.
