I agree. If you're the only user of your instance, they can easily track you server-side by your IP address. You could mitigate this by routing your egress traffic (either from the individual device or network-wide, from your router) through a VPN.
Just remember that you’re still technically trackable via behavioral, configuration, or latency fingerprinting. Anonymity is a full-time academic endeavor, not a shell script one-liner.
