That is where Dandelion routing and anonymity networks comes in.

A global passive observer could track cleartext transaction hashes and flag the first IP seen broadcasting them. Bitcoin peer-to-peer CAN support Tor for transaction routing. Monero blockchain can use I2P to hide transaction source also.

_Most_ adversaries do not have such visibility over global internet flows.
