The thing with VPN's is that you're only shifting the trust from your ISP to your VPN provider. That provider can still see pretty much everything you're doing and your real IP, if they wanted to. To add to this, plenty of VPN companies have been found logging when they said they didn't. I would say either set up traffic for I2P, or simply go with an actually no logs VPN company like Mullvad, who's been battle tested and doesn't log, and you'll be fine.
People also say that because it's important to understand what a VPN is and does as well. It wasn't originally meant to be any sort of anonymity tool, the technology exists to make it seem as if your traffic is coming from somewhere else - which allows for things like remote work on a local network.
