Yeah, the question is what is the proportion of low-hanging fruit versus persistent actors. We didn't just give up on spam because "spammers will find a way around".
And if we can eliminate a bunch of low-hanging fruit (e.g., from consumers who don't care enough about tracking to put a trackable company logo image in their signature), that's better than nothing.
