Without TOR(even with TOR you're still not 100% private, though 99% better than the alternative), your PC/home-router/VPS are 100% public actually, whatever you do can be traced back to you, even the VPS vendor such as DigitalOcean/Linode/etc can connect your IP with you quickly, of course. VPN can secure the tunnel, still you can be tracked to IP/MAC quickly. Same to P2P network such as torrent etc. My take is that when you go surfing, considering the device you used for surfing just like your home mailbox, home address, phone number etc, those are pretty much public info that anyone can find out who you are if they are interested in you.
