Zip files that contain themselves are infinitely large when recursively decompressed, so that's much worse than a log file which is merely easy to compress.
Infinitely large doesn't mean anything, when your disk space is limited.
If your drive is 500GB, there is no practical difference between a 10TB log file a 10PB zip file or an infinite zip bomb... once the disk is full, the unzipping stops.
Narrowly true, except it's trivial to scan a very large archive without actually storing the entire thing, whereas if you tried to do the same thing with a zip quine you'll eventually run out of memory. Zip quines are strictly worse.
