Well they don't actually, Tor especially has enormous amounts of government nodes so they can trace and log exactly what and who. And all of those still rely on the IP network which always will allow logging without you ever knowing, it's just math really, the proof of not-logged is just impossible.

Interesting, do you have a source? All fully p2p networks are vulnerable to sybil attacks to some extent, but specifically a source that Tor actively has enough "government nodes" to de-anonymize everything.
