For many things there isn't really need to get the payload. Get the IP addresses, DNS lookups and TLS SNI information and correlate to information gathered from elsewhere and you can derive a lot.
+1 for the optimism, but unfortunately even with those mitigations it is not enough. Using a VPN in combination with DoT/H is currently best practice I believe.
