I would agree with that if the time to randomize is basically so small that a client can use a unique and un-correlatable address for each connection. Given the data collection abilities and compute resources available to those that want to engage in surveillance, any time for randomizing addresses, be it a day, an hour, or a few minutes, that is greater than this minimum only provides a false sense of security with respect to trying to prevent third parties from making correlations about the sender's identity between different flows on the Internet. Interestingly, CGNAT with enough users behind it can provide these properties (attested by the fact the law enforcement has complained about it).
