Unless you infiltrate someone else's network, the endpoint your basic VPN connects to can always be traced back to you.
So, either you trust a VPN company doesn't hold logs and try to hide within all the other traffic.
Or you host your own VPN on a VPS knowing you haven't set up any logging (and hope that your VPS hasn't been tampered with), but then have a static IP that comes back to your identity.
