The debug stick in Minecraft is a unique item that is exclusive to the game. Most players who play the vast sandbox game will simply select survival or hardcore mode and play it normally.

As previously noted, to get max speed minecarts in Minecraft at the moment through the use of the /gamerule command, you'll need to be playing on Snapshot 24w33a or above and also have cheats enabled.

You can get a command block in your Minecraft Java or Bedrock world using cheats and a special chat command.
