nordvpn (or maybe something more trustworthy than it, like mullvad) is the complete opposite of just routing all your traffic through your own vps, it changes your public IP address making tracking you harder (obviously opsec is important there with browser fingerprinting etc).

If you always go to your own vps then that IP address is tied to you, typically via a credit card.

buy a bunch of giftcards from home depot (or wherever) with cash. wear a mask and glasses if you're really worried.

use those to pay for VPNs, like PIA or Mullvad.
