If the network’s owner was the one doing DNS redirects, couldn’t they just instead use the IP address in the DNSSEC-signed record themselves? I don’t think DNSSEC is a robust protection if you don’t trust the network you’re connected to.

This would break the chain of trust (you wouldn't trust the network's key signing the address for that zone).
The attacker doesn’t resign the DNS record with their own key, they just let the legitimately signed record though and use the IP address in that legitimate record themselves. If someone owns the network (or is an active MitM) they can control where IP addresses route to.
