Do you need a VPN for some jurisdictions? NO. Should you use one anyways for obscurity and privacy? YES. Also to prevent issues with laws in other countries, which is unlikely from the start, but is exactly the point. Most countries only will try and prosecute copyright in their own jurisdictions unless you're uploading and providing content. When a copyright troll firm resolves your IP (usually through torrent swarms) and hostname and it points to a VPN data center or server, they're not going ANY further and they're just going to move on to the next victim.
